C64 Dungeon Play and Lost World Demonstration

Another personal project post! I have done more work in making David Caruso II’s obscure Commodore 64 CRPG Dungeon, published in the issues of the disk magazine LOADSTAR more than once, presentable to current-day audiences. Although it certainly has its limits, there are some aspect to it that are unique, even forward-thinking. We posted about Dungeon here before. To remind everyone, we sell Dungeon on my (rodneylives’) itch.io page for $5, with the blessing of rights-holder and LOADSTAR owner Fender Tucker.

There are a few bugs in Dungeon, now basically impossible to fix, that I’m trying to track down and document, and I’m also working on improving the documentation, as well as provide some useful goodies with the system, like a disk of monsters, equipment and magic items. That’s useful because Dungeon has a special feature where it’ll take the monsters and items on a “Data Disk,” and scatter them around a dungeon map of its own creation. It calls these randomized adventures “Lost Worlds.”

Lost Worlds operate as a kind of quasi-roguelike. The Dungeon software creates a random map and places random items around it, but once created it becomes a Dungeon adventure that any created character can explore as many times as they like. While it doesn’t have roguelike tactical combat gameplay or random item identification, it does have a form of permadeath. Characters only get three lives to advance their level as far as they can go.

Lost Worlds are interesting places to explore, but there are some bugs in them. It is possible, in fact pretty easy, to get stuck in a part of the dungeon from which one can’t escape. Sometimes a one-way door leads into an area that can’t be escaped, and sometimes a passage-blocking trap will strand the player’s character in a dead-end. And once in a while a Lost World is downright unfinishable, its goal item disconnected from the parts of the dungeon the player can even reach.

While there are spells (Passwall and Teleport) that can release a trapped character, if they aren’t available the character is not completely lost. If you turn off the C64 (or close the emulator), then return to the Guild screen, the character will be marked as GONE. Over time, measured in loads of the Guild menu, the character will eventually find their way back on their own. It takes quite a while for this to happen though: I counted 15 loads, saving the game each time, before a GONE character returned.

This video (23 minutes) is is something I recorded myself as a demonstration of both Dungeon’s gameplay, and its Lost World adventure generation. It uses a set of 30 low-level monsters and items based on the stats of the old Basic edition of D&D, and a set of magic items I created for usefulness and to show off Dungeon’s spell set.

So, why would someone want to play this game, when there’s so many other newer CRPGs out there to play?

  • The idea of rolling up a character and taking them through scenarios made by other people, to try to get their level up as high as they can get before they die three times, is great. My hope, perhaps misplaced, is this release will inspire other people to make dungeons for others to play, and I look forward to seeing them myself.
  • The magic system of Dungeon, while it doesn’t allow for characters to learn spells themselves, is unique in that most of the spells are utility spells! There are spells for passing through walls, for teleporting anywhere on the map, for revealing terrain, for seeing in darkness, for giving oneself a damage shield, for locating the goal item, for disarming traps, and more. There is only one direct damage attack spell! Spells are more like tools than something you use to pound through the enemies.
  • The dungeon model allows for dark areas, traps that block exits, two-way and one-way teleporters, secret doors, one-way doors, and decorating dungeon maps with PETSCII graphics. The simplicity of the dungeons, all of them fitting on one screen, works in Dungeon’s favor. No dungeon can be too large since they must all fit within the bounds of the map grid.

There are unique design considerations for making Lost Worlds too. Even though the computer creates the maps unaided, since it populates them from the monsters, items and traps that are on the Data Disk, the difficulty of the resulting dungeon is affected. The various doodads are distributed without apparent heed for what they are; I wonder if the generator actually cares for their identities or if it just checks how many of each type are on the disk, so as not to exceed that number.

If there are more easy monsters, more powerful items, and more weak traps on the disk then the dungeon will be easier due to their corresponding numbers being greater, and vice versa. It occurs to me that one of the flaws in the dungeon generation I mentioned could be alleviated, by not giving it one of the wall creating traps that could trap a player in a dead-end, but that also makes the dungeon a bit less interesting, so I’ve left it in the mix I use.

I recognize that, if I let myself, this might become a Dungeon blog. Rest assured, I’m not going to take it that far. But I really hope that some people give Dungeon a chance. While sure it has its inspirations (one person on Mastodon said it reminds them of Phantasie, a somewhat less obscure early CRPG), I think it’s pretty unique, and deserves for more people to have a look at it. I’m particularly pleased how well the sample monsters and items I made work in the Lost World framework, and I’m trying to think of ways that it might be improved. More on this later… but, not immediately, I think.

RGME: Glitching Mario World by Stomping Wigglers

More Youtube videos coming up! In this hellish age of the World Wide Web, where discovering things with Google Search is harder than ever, at least Youtube has a decent discoverability system (when it works, which is not always). Discovering things has long been really difficult on the internet, what we’re witnessing is just a regression to an earlier state where things appear and disappear unseen all the time, like particles and antiparticles annihilating each other. It’s still a huge problem, we just forgot, for a while, that there’s still no good solution. Um, what was I talking about again?

Retro Game Mechanics Explained (RGME: See? The acronym in the title means something!) recently explained a glitch in Super Mario World, a game that is becoming infamous for its many glitches. Some of those glitches are oversights, but some are the result of features planned in development, and even partially implemented, but then for whatever reason were abandoned.

Most of the enemies in the game, if you stomp on them over and over without touching the ground, give you more and more points and eventually extra lives. But there are indications that, at some point during the game’s development, it wasn’t going to stop there. There is support in Super Mario World for further rewards beyond “1UPs”: 2UP, 3UP, 5UP, and from there, for some unknown reason, coins.

The code in the game supports going into those ranges, but for all the enemies in the game, only one has the support enabled, probably accidentally: Wigglers. If you consecutively stop Wigglers, which is only possible in one or two levels, the cap on the awards for stomping on them is lifted, and the lookups from the table on which the rewards are stores continue, off the end of the table, into miscellaneous ROM space, awarding undefined rewards, and quickly awarding many hundreds of thousands of points.

The full details are in their video, here (20 minutes):

I have a particular fondness for this glitch because I encountered it myself once, long ago, on actual hardware!

Sundry Sunday: Lego Breakfast with Super Mario

Sundry Sunday is our weekly feature of fun gaming culture finds and videos, from across the years and even decades.

tomoseen is a gifted stop-motion animator from Japan, who’s made over 40 videos on Youtube. They make animations with tiny figurines of cats and ducks, food, dice and Lego pieces. All of them are a ray of sunlight, but very few of them are relevant to our subject. In fact, really only one is: a Lego video of breakfast made from Mario enemies. It’s five minutes long, and amazing:

Wait, there is one other tomosteen video that’s slightly game-related: Steak Dinner with Dice has a special guest appearance by Tetris, but it’s not really enough to merit its own post here. Consider it a bonus:

The History of Kid Pix

I feel like I should adopt some standard way to inform people which items are links to other sites (with minor commentary attached) and which are significant longform items of our own creation.

Suffice to say this is the former category. I didn’t write this history of Kid Pix: Craig Hickman wrote it, back around 2013. And he also created the original version of that program too. And it was terrific. Here is the link.

Kid Pix in its original format

What was Kid Pix? It was a paint program for early Macintosh models that was very well-received, and is very fondly remembered. It had a powerful UI but was still, neverthless, aimed at kids. Think of it as a more fun version of MacPaint. I refuse to stay in my lane regarding entertaining uses of computers, but perhaps of more interest to what I’d think are our usual readers, it had a similar concept to the art module of Mario Paint, but came out at least a couple of years earlier.

I especially like how he described the original Macintosh UI as having “a consistent and enlightened vision behind it,” which I’m not sure can be said of Macs today, or really of the products of any major software company. That’s just my opinion, mind you.

Did you know there is a Javascript re-implementation of an older version of Kid Pix? Here!

Moviecart

After a long day in the data mines, it’s certainly nice to come home, walk over to the movie shelf, select a movie to watch, then put it into my movie player of choice: an Atari 2600. A demonstration (40 seconds):

Moviecart’s actually been around, judging by the date on that video demonstration, for at least three years now, but is currently accepting preorders for $25. The video only uses half the screen, and has glitches and distracting horizontal and vertical lines running through it, but at they say, it’s amazing that the dog talks at all. Or in this case, that the dog can display roughly arbitrary video and sound, two things the Atari usually finds it impossible to pull off.

How is it done? With custom hardware, certainly, but even granting that there’s only so much that can be done with the VCS/2600’s display chip, the restrictive funnel through which the cart’s video must be squeezed.

After that, getting all that data to the screen is done through presenting it to the VCS/2600’s address space at the absolute limit of the system’s ability to use it. The real work is done by a processor on the Moviecart’s board, which handles reading a specially-encoded video file on a Micro SD card and doing all of the work in getting it ready for the screen, so the VCS’s 6507 processor has to do as little as possible itself.
