M.U.L.E. Turns 40

Dani Bunten’s classic economic simulation M.U.L.E. is one of the all-time greats, still fairly obscure even among people who know and talk about video and computer games, but hugely influential. Wikipedia tells us that Shigeru Miyamoto considers it an influence on the Pikmin games (although other than in theme I really don’t see it).

There are three current ways to play M.U.L.E. One is Planet M.U.L.E., an official port sponsored by Ozark Softscape, which is several years old, and I was certain I had posted here about before. It’s a proper update with new graphics and a lot of character. A thing about M.U.L.E. is that the original versions were intricately designed in a lot of ways, not just in game rules but the little details. The way the phase ending noise speeds up, the exact difficulty of catching a Wampus, the speeds with which players walk through terrain, the many details of auctions, even the time it takes to outfit a mule and leave/enter town, it’s all finely calculated. You can tell that Dani cared deeply about the game, and it’s a polished as any game I’ve ever seen, and that’s the old 8-bit computer versions. Planet M.U.L.E. isn’t as polished, but it’s still very nice, and you can tell its makers thought hard about it. It offers both local and online play.

Sadly, Planet M.U.L.E. seems to be on life support. While games can still be played, and the automated best player posts still go up on its blog, it’s not gotten an update in years, and it’s even possible they’ve lost the source code.

One legacy of Planet M.U.L.E. is a wonderful Youtube video they made that explains the game and how to play. It’s a great introduction:

M.U.L.E. Returns was a mobile port. It has a website, that’s still around, but apparently none of those versions are available. It’s got a page for a Steam version, but it’s not available despite the original game being released in 2013. The site claims it may come back some day, but it cannot be purchased currently.

Then there’s the new roboanimal on the block, M.U.L.E. Online, which is on itch.io for a very reasonable $5. It has the blessing of Ozark Softscape, and is a near match for the Atari 800 version. You won’t get any improved graphics or sound here, but you will get a game that copies the original very closely, which is perfectly fine in my opinion. It offers local single and multiplayer, as well as internet-based online play. They also promote a board game version of M.U.L.E, which I’ve long wanted to try!

Or there’s emulation. Back in college I played M.U.L.E. with roommates via an Atari 800 emulator burnt to a Dreamcast disk, a great way to play if you have the system, controllers and means to construct the disk because the Dreamcast has four controller ports. (M.U.L.E. is by far at its best when you have four people playing.) The Commdore 64 and IBM PC versions were also made by Dani and the others at Ozark Softscape. The C64 port is close to the Atari 8-bit version. I don’t know about the DOS PC version. I can say that the NES version made by Mindscape is a terrible version, while sadly possibly the most-played because of the great popularity of the NES. If you tried that version and wondered what the fuss is about, you should seek out the Atari 8-bit version and play it before writing off the game entirely.

World Of Mule is a fansite dedicated to M.U.L.E. in all its forms. For its 40th anniversary, they’ve published a long retrospective on the game, its history and the new versions. (That’s where the above image comes from.) It’s a fitting tribute to one of the most influential computer games ever made.

Long ago, on primordial wiki-like site everything2.com, I personally wrote a long examination and play guide to M.U.L.E. While my writing style back then was pretty crazy, I think the information holds up. If you have an interest, you may want to take a look.

The Graphics of Trap Door and Popeye on the Commodore 64

In my teens I got started coding on my old Commodore 64s. Learning to program was a much different process back then, there was no internet to answer basically any question you’d have almost on a whim, everything I picked up came from some written matter, mostly programmer’s guides (including the definitive guide to using the hardware, the Programmer’s Reference Guide) or periodicals like Compute’s Gazette, Ahoy! and Commodore Magazine.

The C64 had a lot of graphics features, made possible by the machine’s powerful VIC-II chip. All of the home computers of the time had tricks one could use to get extra mileage out of their bespoke graphics hardware. The Atari 8-bit computers had display lists, for instance. The VIC-II had a powerful raster interrupt facility, the ability to share memory with the processor (at the cost of delaying the whole machine while it did so), eight surprisingly large hardware sprites (in double-width mode they could fill a whole scanline, something the NES’ sprites could only dream of doing), and a collection of interesting and flexible graphics modes.

Most of the time the C64 was in character mode, which was the standard kind of tile-based mode that pretty much all home computers at the time used by default, suitable for displaying messages, coding and some graphics. The ’64 three such modes: the standard mode where each character had a single color along with the screen-wide background color; a multicolor mode that gave a character its own color, up to two colors shared throughout the screen and that background color, and (mumble mumble). Sorry, what’d I say? I’ll get to that later.

The system also had two bitmapped modes that worked similarly, just directly viewing a region of memory instead of using each byte as an index into a character set. One mode was like the standard character mode, where the 1s in the bitmap were colored and the 0s were the background color; the other was multicolor mode, which similarly worked like it did in multicolor character mode: one color per 8×8 region, two colors shared throughout the screen, and the background color.

The problem with multicolor mode was, you had to trade horizontal resolution to use it. The big limiting factor to many computers’ graphics then was memory use: finding a way to encode the graphics information so the chip could access it and convert it into a video signal quickly enough to meet the needs of the display. So, to fit an 8-pixel-wide section of screen into the single byte it needed to be squeezed into, it could either use a one-to-one dot to screen ratio, or sacrifice two bits for one extra-wide pixel of up to four possible colors.

UNLESS

The Commodore 64 had a fifth graphics mode. The one I mumbled over earlier. The much-ignored Extended Background Color mode.

It was another character based mode that, instead of forcing you to make use of one background color over the whole screen, gave you up to four such colors. Every cell on the screen could display a character using its full 8×8 resolution, but could also pick which of those background colors it could have. Useful!

Well… not as useful as you’d think. There’s always a tradeoff, and Extended Background Color’s tradeoff was a dire one. How does the VIC-II chip know which background color to use for each character cell? It uses the two high-order bits of each character byte. Meaning, while you could decide which of two colors would be used in each cell with a lot greater nuance, you only had 64 characters to work with! A full screen of 1,000 characters is a lot to fill with just 64 possible tiles. A lot of repetition would be unavoidable, which is probably why it was so little-used.

It essentially was either this:

or this

These images are a little misleading, because I used the Commodore 64’s default ROM character set to make them, and the second half of its characters are just mirror images of the first half. But if you define your own characters, which basically any game worth its salt will do, it greatly reduces the number of tiles at your disposal. There may be some sneaky ways around it, sure, but they all involve their own tradeoffs.

I explain all this because Extended Background Color Mode is my best guess as to how Trap Door and Popeye do their graphics.

Here’s video of a playthrough of Popeye. It’s about 21 minutes, but it shouldn’t take long to get what I mean. It’s not Nintendo’s Popeye, it’s a completely different game.

And here’s a playthrough of Trap Door, with graphics by the same person:

Look at those huge characters! How could this be possible, and with that color depth? The C64 can have huge sprites, but only at the cost of making all their dots twice as tall and/or wide. And the pixels aren’t even multicolor mode wide. I can’t quite make sense out of it! Unless, maybe the games are displaying their large characters using the character set, which explains why they jerk along the screen? And the colors are using Extended Background Mode? That might explain the simplicity of the backgrounds, with only 64 characters to work with that means a lot of reused tiles.

I guess the point of this post is: what gives?

On PETSCII

We’ve brought up a couple of examples of Commodore PET software lately, which as I keep saying, is interesting because the PET has no way of doing bitmapped graphics, sprites, or even definable characters. Its characters are locked in ROM and cannot be changed. So, it includes a set of multi-purpose characters that was used throughout all the Commodore 8-bit line, even as late as the C64 and C128, which having definable graphics didn’t need these kinds of generic graphics characters, but they were still useful for people who didn’t want to create their own graphics.

The PETSCII characters, as used on the Commodore 64 (image, with some editing, from Wikipedia). The graphics set also includes reverse-video versions of each character.

Back on my Commodore coding days I became very familiar with these characters. I think they’re much more universally-applicable for graphic use than the IBM equivalent, the famous Code Page 437, although that’s mostly because PETSCII doesn’t bother defining supporting so many languages. Code Page 437 also uses a lot of its space for single and double-line versions of box-drawing characters, although on the other hand it doesn’t waste characters defining reverse-video versions of every glyph.

PETSCII has:

  • A space and reversed space, of course.
  • Line drawing characters for boxes of course: vertical and horizontal lines, corners, and three- and four-way intersections. There are also curved versions of the corners.
  • More line-drawing characters for borders.
  • Still more horizontal and vertical lines, at each pixel position within their box.
  • With the reverse-video versions, enough characters to effectively do a 80×50 pixel display, as if it had a super low-res mode.
  • Different thicknesses of horizontal and vertical lines too.
  • Diagonal lines, and a big ‘X’. Note that on the PET and Vic-20 these lines were all one pixel wide, but on later computers with both better resolution and color graphics they were made thicker, which means diagonal lines have “notches” between character cells.
  • Other miscellaneous symbols: playing card symbols, filled and hollow balls, and some checkerboards for shading. On the PET and Vic, the shading characters were finer, while on the other 8-bit computers they were made of 2×2 boxes.

There are resources that let you use PETSCII to create old-school computer art, like this PETSCII editor, Petmate and Playscii, and for a bunch of examples of what you can do with it you can browse through the Twitter account PETSCIIBots. And this blog post from 2016 both makes the case for PETSCII as a medium for art and provides some great examples of it.

Loadstar!

Now is the beginning of a fantastic journey!

Aah that’s a screen I haven’t seen in a long long time.

1982 saw the founding of the Apple II computer magazine-on-disk Softdisk. Soon after Softdisk Publishing produced disks for other home computers too. One of them, Big Blue Disk, has gone down in history as previous employer of some of the original principals of id Software, especially John Carmack and John Romero. But another of Softdisk’s legacies was their Commodore 64 product, Loadstar, probably the longest-lived Commodore 64 software publisher. They published C64 software from 1984 to 2007. And most, if not all, of it is available online!

Loadstar is yet another of those computer gaming stories that must be told, and I’m in a pretty good place to tell some of it, because I beta tested for them for many of those years, and sold programs to them as well. Yes, several of their releases bear the programmer name John “The Mad Gamer” Harris. You have to understand, this was long before the word gamer reached common usage. In fact, as someone who may have primacy over the use of the term, I hereby forbid its use by anyone with misogynistic, anti-trans or racist intent. It is so decreed, hey-nonny-nonny!

Loadstar was lots of fun. Every month they’d send you two disks in the mail with several new pieces of Commodore 64 software on it. Under the watchful eyes of Fender Tucker and Jeff Jones, and later on Dave Moorman, it’s not that they grew an empire of Commodore programs, but they did manage to sustain that platform for a small but avid userbase for far longer than you’d have thought possible.

I plan to start doing Loadstar reviews eventually, but in the meantime, you can try out some of the later issues of this important piece of computing history at the site linked below. Note that you’ll have to have a means of running C64 software to use them, of course. The emulator VICE is known to work well. And if you want to hear the words of Fender, Jeff or Dave yourself, all three are on Facebook.

News 1/24/22: Pokemon Collecting, Universal Mario World, Commodore 64 of Theseus

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

Let’s make it quick this week-

Oli Welsh at Polygon tells us what we already knew, that No Zelda Game is Closer to Breath of the Wild Than The 1986 Original. We can’t recommend it whole-heartedly though because it gets in some digs on the older game, saying it’s nowhere near as much fun as Link to the Past, a statement I disagree with.

Hope Bellingham at GamesRadar tells us that U.S. Customs wrecked a sealed-in-box copy of Pokemon Yellow valued at over $10,000. I rather disagree with that valuation too. I thought all the misguided young people were losing their money in crypto these days? (Note: GamesRadar is one of those sites that waits until you start reading an article then puts up a blocking box begging you to subscribe. Hint to GamesRadar: NO, and if I were interested in subscribing my generous impulse would have been destroyed by your prompt!)

Image from The Guardian, probably ultimately from a promotional photograph

At the Guardian, the very British-named Oliver Wainwright reviews Super Mario World, not the game but the theme park in California, a part of Universal Studios Hollywood. The verdict: 8/10, good graphics, some replay value. I’ve been in a melancholy frame of mind as of late, so seeing those brightly-painted dioramas makes me wonder what they’ll look like in twenty years, when Universal Studios’ attentions have drifted to another big thing. Nothing ages quite as badly as a happy prop painted in primary colors.

I said I was going to make this quick, let’s keep moving. Maya Posch at hackaday talks about a project to build a Commodore 64 using new parts.

Ollie Reynolds found some Donkey Kong design documents on Twitter, from the days when it was planned to be a Popeye game. He found them retweeted by blogfriend Mike Mika of Digital Eclipse, who in turn found them looking through Mario history site Forest of Illusion.

RenoProject.org: Documenting Habitat and its descendants

Long, long ago, three full ages before Zuckerberg’s doomed Metaverse, there was Lucasarts, formerly Lucasfilm Games, and Maniac Mansion, and the SCUMM engine.

Lucasarts went on to have a long legacy of adventure games, and while it’s gone now and most of its progeny is owned by some mouse creature, it survives in a number of forms, like the upcoming Monkey Island re-revival.

Another legacy of Lucasarts and SCUMM is what is possibly the first graphical MUD, called Habitat.

Even though it’s blurry, it deserves the head spot on a blog post, just one more time.

What? You don’t know what a MUD is, or a MOO or a MUCK? A lot of knowledge is in danger of being lost, but we don’t have time to remind you of rudiments here.

Habitat was an early experiment in online communities, a server-based virtual world whose clients were Commodore 64s. In appearance it looks a whole lot like a multiplayer version of Maniac Mansion.

It never went public, but did eventually become a paid feature, in modified form. on the C64 online service QuantumLink under the name Club Caribe. Then, with the wane of the Commodore 64 as a viable platform, QuantumLink closed their servers and rebranded as America On-Line, a.k.a. AOL. And that is not only history at this point, but ancient history. Read more about it here.

While there was still competition in the dial-up online service space, two creators of Habitat, Randy Farmer and Chip Morningstar, partnered with Fujitsu to have another go at a Habitat-style service, this time called WorldsAway. They partnered with AOL competitor CompuServe, and didn’t do badly for a while.

There’s all kinds of things to talk about here, and I have rather more knowledge than most because I was involved with this, I was volunteer staff at the flagship WorldsAway world, called Dreamscape. I was a participant in the CompuServe forum before the main service even opened, I spend an entire night on the phone as a teen, our old 486DX running Windows 3.11 downloading the client software.

WorldsAway was basically my life for a few years. It could be incredibly addicting, and spirits were high in the early days. There was a feeling of being at the forefront of something. The Internet was just starting to become really big. Who knew what it would become?

What happened to WorldsAway is a story, one that I’m probably not qualified to tell. I know there were problems with business management even from the start. The world staff was constantly said to be fighting with higher-ups, who wanted to cheapen or diminish the project. In size, certainly, the initial world Dreamscape never got anywhere as large as what we hoped for. Even compared to the size of its Commodore 64 predecessor Club Caribe, it was pretty small.

It’s said that they were a west coast operation, and many of their staffers were queer. One of the eventual spinoff worlds that WorldsAway would spawn was explicitly queer-friendly. Given the successes and continued struggles of queer-friendly media on the internet today, I feel like WA’s acceptance of alternate lifestyles should probably be better known.

I still have a couple of friends from those days. Others I’ve sadly lost touch with. A few friends from that time, notably Tiggles, Esme, and Rosaleah, have departed our physical world as well. Maybe some comfort could be had in the idea that maybe they’re users in some higher-order reality, who may have logged-off of our world, but are still out there in a more profound form. If they’re out there and somehow seeing this: please spare a thought for me. I’ll be back out there some day.

The Reno Project is a website devoted to preserving as much of those early projects, those ancient times, as possible. You could immerse yourself in the screenshots there, and dream of a past era that barely was. One of its competitors at the time, which is a bit better known today, is The Palace. One other service that still exists that competed with it is There, although good luck making an account (I tried). And Second Life of course continues to chug along. All of these things seem to me like more worthy projects than Zuckerberg’s latest progeny.

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

It’s been a bit difficult getting consistent signals from Earth lately, and what has gotten through hasn’t been of too much interest to my gelatinous brain. Maybe some of this might pique your interest?

Jonathan Bolding at PC Gamer says that playing dual-screen with a Steam Deck proves the Wii-U was a good idea! I knew it! What they’re talking about is the ability of a Steam Deck to play dual-headed via HDMI out. This play style is explicitly supported in Wii-U emulator Cemu. The article also notes that Valve has stated that the Steam Deck has out-performed sales estimates, which is good! After the Steam Link and Steam Controller were put on sale for ultra-cheap, I was feeling bad about scooping them up as Valve was clearing out stock. Not too bad, though.

SMB3 Scribe’s tile selector

Here’s some news from a different source than usual. At romhacking.net, creator Michael Nix has been working on a pair of GUI rom editors for Super Mario Bros. 3! One, SMB3-Foundry, is for editing levels, and the other, SMB3-Scribe, edits overworlds. A game like SMB3 is a bewilderingly complex beast under the hood, and the strictures of platform, rom space and development time sometimes force unorthodox decisions, like hardcoding some object placements. There is an article to be written some time about the lengths NES carts had to go through to encode their data, which was usually done using a kind of domain-specific data compression.

SMB3 Foundry’s level editor

I have been avoiding linking CBR.com for a bit because of some excessively clickbait headlines, but a recent device change has reset my killfile, so they’re back. Shane Foley from there reports on series nadir Metroid Other M having one level that made it worthwhile. The “level” in question is in fact the entire postgame; up until the main boss, the whole game is heavily on rails, with full exploration only possible afterward.

At Polygon, Nicole Carpenter mentions the content warnings on new indie title I Was A Teenage Exocolonist, which has a number of traumatic events in the game, but is quite upfront about what will occur, going so far as asking the player if they’d like to be spoiled regarding which characters die, or may die. It is a heartening development.

Keith Stuart at the Guardian has a retrospective on gaming on the Commodore 64 at age 40. That old huh. Naw, that doesn’t immediately paralyze me with fear.

(Note: the Guardian is in one of those phases where they nag you with a huge yellow subscription ad. It can be easily closed, and not nearly as bad as some sites out there, but it happens. One article I checked this time-I will not link them-had autoplaying overlaid videos in the corner, which resulted in them being ejected from this post. Bad web designer, no biscuit!)

Baba Is You

Shaun Musgrave at Touch Arcade lists the best recent iPhone game updates. Mentioned are Baba Is You (yay!), Genshin Impact, and Mini Metro (yay again!).

Destructoid’s Chris Carter lists Switch games that make substantive use of the right Joycon’s IR sensor.

Blogfriend Kyle Orland at Ars Technica reports on Fabrice Breton, creator of indie game Brok the Investigator, and their efforts to track down Steam key scammers, curators who would ask devs for free Steam keys but then sell them. As usual from Kyle it’s great and informative reading!

From Alice Newcome-Beill at The Verge, a report on a new version of a Switch Pro controller from 8BitDo, who seem to make good products, although they note they have not yet received the controller for testing.

I’m sure I won’t see this image a thousand times over the next few months drebnar.
(Source: Lorcana’s official Twitter feed)

And for our weekly eyeroll exercises, it’s been reported everywhere but GamesRadar hasn’t been seen in these pages yet so let’s give the link to them: Benjamin Abbott relates that Disney is releasing a Magic: The Gathering style trading card game going by the name of (roll your eyes now!) Lorcana. I’m already brainstorming jokes to make about it as they leak its features over the coming weeks!

K.C. Munchkin for Commodore 64

The always great Indie Retro News mentions, from Pretzel Logic, a Commodore port of one of the best Odyssey 2 games, K.C. Munchkin (itch.io, $0)!

Why is this interesting? The machinations of the old old days of video games are so easily forgotten now. K.C. Munchkin was a big seller for the underdog in the second-generation video game sweepstakes, but was taken off the market by court order way back then for being too similar to Pac-Man. Although Magnavox managed to come back a bit with sequel K.C.’s Krazy Chase, they remained a distant third in the market.

The C64 version has multiple modes, including a random maze mode and editor like the original, also has an arcade mode with 96 mazes!

Video: Easter Eggs in Classic C64 Cartridges

The always terrific 8-Bit Show And Tell shows us some secret codes for old cartridge-based C64 games that reveal they were developed by Andy Finkel. These are recent finds! I had the C64 port of Lazarian growing up, and much later I was surprised to find out I prefer it to the arcade version, the C64 version feels more polished and has better music!

Along the way we’re also taught about the super-obscure Commodore product the Max Machine, which is like a severely stripped-down C64 with a bad keyboard, no ports for storage devices, and only 2K of RAM, but including the C64’s iconic VIC-II and SID chips. It was designed solely to run cartridge software. The Max is mentioned on the C64 Programmer’s Reference Guide, where I saw it long ago and had to wonder what the heck that was about. Turns out the Commodore 64 has a compatibility mode that lets it run Max Machine carts!

The Max Machine only saw release in Japan, where it was very obscure. Just think, if Commodore had put a full 64K into that, maybe it could have supplanted the MSX? Well maybe not, but it’s interesting to think about!

News 7/31/22: Overwatch Tournament, Vestaria Saga, C64OS

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

Shaun Prescott at PC Gamer notes that Steam going forward is banning the use of award icons and review scores in the main graphical assets within their store. This is the “key art,” which I believe is the stuff that heads a store page. Readability is a given concern, in order not to shrink the game’s logo to make room for a muddle of icons and text, and also to be more considerate of non-English speaking users.

Luke Plunkett at Kotaku: it seems Blizzard changed the rules during an Overwatch tournament, making a set that was intended to be best-of-seven into best-of-five while it was going, causing players to refuse to play in protest. In retrospect it seems like it may have been a result of confusion among the event’s organizers.

Graham Smith at Rock Paper Shotgun: the original creator of Fire Emblem has been making games in its style independently, Vestaria Saga and Vestaria Saga II. They’re designed by Shouzou Kaga working with volunteers over the internet, using a package called SRPG Studio, which is represented in the article as free, but costs $60 on Steam. Similarly, while Vestaria Saga II is free in Japanese, a translated English version is on Steam for $20.

Ollie Reynolds at NintendoLife makes a case that Super Mario Sunshine is the best 3D Mario game. It is quite underrated! For those who haven’t kept up, that’s the Gamecube version, which was also included in the limited release Super Mario 3D All-Stars on Switch and nowhere else.

Screenshot from Hackaday

And it’s not strictly gaming-related, but Bryan Cockfield at Hackaday keeps us appraised of the progress of a modern-ish OS for Commodore 64 computers! It’s called C64OS. People who have followed the 64 since olden times know this isn’t the first, or even the second, time this has happened. This project uses a character-based display to show its buttons and windows. It’s worth noting that it isn’t out yet, and it’s intended to be a paid offering, not something which one can just download and tinker with, which may limit its reach. Still though, it’s an interesting idea, and one that can take advantage of some of the C64’s more advanced peripherals, like mice, ram expansions and WiFi modems.

Tutankham Returns

Tutankham Returns (itch.io link, $0) is a port/expansion of the classic Konami/Stern arcade game Tutankham. While Tutankham had only three levels, this has seven, but otherwise is much the same kind of thing. Compare the above to the original. It matches the original’s sound, graphics, and presentation exactly! The games have especially good sound design.

Creator Luca Carminati has a number of other recreations of classic games in itch.io, some, like a version of Tutankham Returns, for the Commodore 64. (Yes, it’s another Commodore post!) Of particular note is Bagman Comes Back (video, C64), a port of another neglected classic, with 24 different maps, compared to the original’s single three-screen board. Luca has been in this for a long time; he has a collection of Amiga games on itch that he made starting back in 1995!

Vision BASIC for the Commodore 64

The Commodore 64 was, for its time, quite a wonder, an inexpensive home computer with 64K of RAM and excellent for its time graphics and sound capabilities. Sadly, it came with one of the more limited versions of Microsoft BASIC out there.

Microsoft BASIC had its strengths, but many of them were not a good match for its hardware. The C64 had no commands to take advantage of any of its terrific features. To do nearly anything on the machine besides PRINTing and manipulating data, you had to refer to a small number of cryptic-yet-essential commands: POKE for putting values into arbitrary memory addresses, PEEK for reading values out of them, READ and DATA to read in lists of numbers representing machine language routines, and SYS to activate them.

And getting the values to do those things required obtaining and poring over manuals and the venerable C64 Programmer’s Reference Guide. Even then, Microsoft BASIC was notably slow, especially when doing work with numbers, due to its dogged insistence of converting all values, including integers, into floating point before doing any math on them. So while BASIC supported integers, which required less memory to store, actually slowed the machine down due to the need to convert to and from floating point whenever an operation needed to be performed on them. This doesn’t even begin to get into the many inefficiencies of being an interpreted language.

Vision BASIC, an upcoming commercial compiled language for the Commodore 64, looks to remedy many of these faults. The above video is a nearly 40-minute explainer and demonstration of the system. It requires the purchase of a memory expansion unit in order to be used on a physical machine, but it can produce executable code that can be run on a stock C64 as it came out of the box.

It’s not free, and at $59 for the basic package it may seem a little high for a system for developing software on a 40-year-old computer, but that price includes the software on floppy disk and a USB drive. It’s certainly capable, and runs much faster than many other compiled languages on the system. It’s definitely something to look into for people looking to make games on the system without digging deep into assembly, and if you have a desire to do that it has a built-in assembler for producing in-line machine code too! It is an intriguing new option for Commodore development.
