Romhack Thursday: Super Mario World Coin Chaos

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

You could consider the act of creating a romhack to, itself, have difficulty levels.

The easiest kind of hack to make, usually, is the simple graphic hack. Most game engines don’t really care what its characters look like, it just tells the hardware where in memory to get the data to display the game objects. If you only change the graphics, the rest of the program is none the wiser. That’s why there were so many dumb visual hacks in the early days of romhacking.

Up one level of difficulty is the level edit. These can be pretty hard if unaided, but many games these days have bespoke map editors. Many classic-era games don’t store their area data internally as tilemaps, meaning it’s not quite true that you can change game levels to just anything, and many of these programs are not simple to learn or use, but it beats finding and editing pointers directly out of the game’s binary code.

A fairly difficult thing to do is to modify the game’s engine itself. Platformer engines are complex mechanisms, especially back in the days when they had to be highly optimized in order to leave time in each frame for other necessary game logic. Many Game Genie codes modify engine operation, but many of those same codes make the game glitchy and prone to crash. Especially if the modifications involve the creation of additional game states, that not only must interface with the rest of the game’s code without breaking things, but must also have room found for them inside a typically crowded game program.

Super Mario World Coin Chaos, by Jp32, doesn’t change the engine much, but makes them count. A few of them:

  • Mario has unlimited lives, which isn’t an uncommon change for a hack like this.
  • Mario’s health isn’t determined by his powerup state. 1Up Mushrooms have been repurposes to add a hit point, up to five. Powerups affect his abilities but don’t give him any extra hits.
  • Fire Flowers grant a limited number of fireball shots. One level, Frozen, starts Mario out with them, and offer additional shots.
  • While underwater, holding down Y allows rapid swimming, as if Mario were holding an item.
  • The level Automatic is an autoscroller, but with a twist: Mario doesn’t have free travel throughout the screen, but moves forward automatically at walking speed.
  • The level Climb grants Mario a wall jump! Like many game wall jumps, it’s hard to get used to, and requires tricky timing.
  • Yoshi can fly forever, but Mario takes damage as usual while riding him.

The biggest change, though, is that instead of trying to reach a goal, Mario is trying to collect coins by whatever means he can. When he gets his 99th coin the level immediately ends.

In difficulty, the game isn’t Kaizo-hard, but it heats up rapidly. The first level is about as hard as a later Super Mario World level, and it gets tougher from there. There are two tracks of levels and the player can progress along either, but both are pretty tricky. I’ve gotten about two-thirds the way through so far, so if there’s any objectionable content after that point, well, mea culpa.

The variety of themes and how they affect the 99-coin objective make this a hack not to miss. It’s not very long in number of levels, but there’s a lot of challenge here waiting for you. Good luck!

How Gravity Works in Super Mario Galaxy

Another Youtube video? Yeah I know. This one explains how gravity works in Super Mario Galaxy. It’s 29 minutes long. The basic gist is, there are eight kinds of invisible gravity field objects, based off of simple shapes, in the game, which are used in concert to create the various orientations that Mario switches to as he moves around: Parallel, Sphere, Cube, Disk, Torus, Cylinder, Wedge, Wire (basically an arbitrary path in space), and Cone, which is only used in two places.

An interesting fact from near the end of the video: gravity affects Mario’s shadow! Shadows point towards where Mario will fall, not according to how light strikes him, to give players a sense of where he is spatially in 3D space.

Super Mario Bros Level Glitches

The Youtube channel Retro Game Mechanics has done a series of three videos on glitches in Super Mario Bros. One involves using the NES game Tennis, which has a certain property of its code that allows you to load all kinds of funky levels in SMB.

They’re all interesting, but the one that floats my particular boat is the third, which turns into a deep dive in the compressed manner that Super Mario Bros. stores its levels in ROM, and uses to draw them during play in real time.

Princess Peach Through The Years

Wonderful blog Thrilling Tales of Video Games did a retrospective last month that went through all the various versions of Princess Peach there’s been. Interestingly, while Peach’s look largely solidified in the promo art for Japanese Super Mario Bros. 2 (the insanely hard one, a.k.a. “The Lost Levels”), before that there were all kinds of takes on the character, ranging from Miyamoto’s own drawing (used in the box art of Super Mario Bros. in Japan) to a variety of versions all trying to adapt her single sprite image from the ending of SMB.

And this is the first version of modern Peach. (Image from blog)

The post features a whole bushel of Peaches, many barely seen outside of Japan. Recommended highly!

Romhack Thursday: Super Mario 64 Reduced Lag

It’s not so much a hack as a recompilation, but it’s distributed in patch form so I’m accepting it. A person identified as “Nintendo 64 Wizard” took the source code created by decompiling Super Mario 64, and, simply, did something that Nintendo didn’t do: compile the game with -O2 optimization turned on. The result is a much more consistent frame rate.

From the romhacking.net article, a scene from the star with Bowser’s Sub in it, which is notorious for causing the game to lag.

If optimizing Super Mario 64 is an appealing concept to you, you might be interested in some of the videos made by Youtuber Kaze Emanuar, that goes into why the game has lag, and his own efforts into improving it.

U Can Beat Video Games: Super Mario Bros 3

We’re brought up U Can Beat Video Games before (here’s all of the videos they’ve done to date, and here is their home page with a merch store), but this time they’ve covered Super Mario Bros. 3 in their typically completionist style, covering every level and every secret in the entire game. Sometimes they split a long game into two or even three videos, but not this time, this one video goes through the whole game, and it’s three hours and 23 minutes long! The other reason to link them this time is it’s their 100th video!

They’ve done some other interesting games since the last time we linked them, which was when they covered A Link To The Past. Some particular games they’ve done in the meantime:

Even if you don’t have an interest in seeing these games taken apart so thoroughly, many people enjoy using their videos as background while doing other things. In a Youtube environment where video makers feel encouraged to go nuts with editing and fill their footage with distracting noises, UCBVG is a model for how to create interesting and informative videos. They are great! And they have a couple of adorable dogs who appear in every video, too!

Arcade Heroes Reviews Mario’s Arcade History

Image borrowed from Arcade Heroes-so that I can promote the post it came from!

It’s a great article! It starts out covering the classic-era games everyone remembers, Donkey Kong, Donkey Kong Jr. and Mario Bros., and then slowly gets less and less well-known. It even mentions the two Gottlieb pinball games!

The Secret of SMB’s Hidden 1UP Blocks

Super Mario Bros. has 10 “1UP” blocks throughout its eight worlds. One of them is in World 1-2, and another is in world 8-2. These are visible (although they appear to be ordinary bricks when hit), and always produce a 1UP Mushroom when hit.

But also, there are a total of eight other 1UP Mushroom blocks in the game. These are hidden, invisible and intangible unless struck from beneath. That causes them to appear and produce a 1UP Mushroom… sometimes.

The 1UP blocks are always in the first level of each world (1-1, 2-1, 3-1, and so on.). They also always appear if you start on that level (say, using the level selection feature unlocked after finishing 8-4) or if the player has just warped to that level. But in other situations, the block usually doesn’t appear.

Image from Stephen Lindholm’s website. Text is from Nintendo’s “How to Win at Super Mario Bros.”

What causes them to appear? Even Nintendo’s guide authors at the time didn’t know. Depending on the source, it either had to do with whether Mario was big when he hit it, or whether he found all the coins in the previous world.

Stephen Lindholm’s website has the details on the true criteria, and you should read it there, but to summarize:

  • There is a flag in the game that is set when a game is begun, when the player warps, or if the player has collected a certain number of coins in the third level of the previous world. 1-3, 2-3, 3-3, etc. That is the deciding factor.
  • How many coins is needed? In World 1-3, it’s all but two. In all the other X-3 levels, you must collect every coin! The game has a short table in its code for the minimum number of coins necessary to earn the mushroom on each level.
  • If you do this, the flag is set. When you get to the following world’s first level, when the 1UP Mushroom block would be generated by the game’s world building code (which operates off the screen to the right of the player’s location), if the flag is set, the invisible block is placed and the flag is unset.
  • If the player dies before collecting it, or never hits it, either way the mushroom is lost.

Romhack Thursday: Vs. Super Mario Bros on NES

On Romhack Thursdays, we bring you interesting finds from the world of game modifications.

Nintendo is a company with a long history, having gotten started making playing cards. They jumped into the video gaming market, like a lot of companies, making dedicated consoles that were released only in Japan. It was the release of the arcade game Donkey Kong that started them on the path to becoming the worldwide success they are today.

Title screen for the Vs. Super Mario Bros hack

The sales of Donkey Kong, and successor games like Donkey Kong Kr., Donkey Kong 3, and Mario Bros., put a lot of Nintendo cabinets out there. In the mid 80s there arose a market for upgrade kits, an alternate set of internal components for an arcade machine that could make it into a new game for players to enjoy. Simultaneous with the success of the Famicom and NES, Nintendo sold a kit called the “Vs. System” that their old cabinets could be converted into, as well as dedicated cabinets that used it.

Among the software Nintendo made for their Vs. cabinets, so they made special arcade versions of many of their NES cartridges for it. Many of these are expanded versions of the originals, with new features. We’ve already looked at Vs. Castlevania, a version of Castlevania remixed for the Vs. Unisystem by Konami. One of these updated versions was of Nintendo’s first huge Famicom hit, called Vs. Super Mario Bros.

Hey, that flower’s supposed to be a 1 Up Mushroom!

Vs. Super Mario Bros. seems, at first, a lot like the original game. It’s got a high score screen and some other minor changes. Players familiar with the Famicom/NES version will find that it changes significantly as they get further into it. Many later levels are completely changed, and much harder. When Nintendo released the Japan sequel to Super Mario Bros., they used levels from the Vs. System port to help flesh it out.

Many changes were made to the game to support arcade play. “Loops” where players could farm extra lives were toned down or removed, extra lives in general were reduced in number, and warp zones don’t take the player nearly as far into the game. Another change made was to add operator adjustable difficulty, allowing the cabinet owner to set how many coins were needed for an extra life.

SUPER PLAYER’S

Through emulation, Vs. Super Mario Bros is completely supported in MAME. But for technical reasons, you can’t just play MAME roms in an NES emulator. If you’d like to play it in the emulator of your choice, or have a means to get it running on actual hardware, creator BMF54123 applied all of the play changes of the arcade version back into the NES version of Super Mario Bros., and even added a title screen that allows you to apply the same difficulty settings that were available to an arcade operator.

Expect a number of tricks that would later get reused in the Japanese sequel to Super Mario Bros.

If you’ve never played Super Mario Bros before… then wow, I’m impressed you even found this blog. But also, this is perhaps not the best way to experience the game now. The demands of arcade design make for a much more challenging experience than the original. If you’re very familiar with the home versions, though, it can be an interesting new way to experience it.

Sundry Sunday: Mario Twins

This one’s really going back a ways. The description on this 2012 video says it’s a Newgrounds classic, and I was not a habitué of that site then, I’m sure it goes back to at least 2005.

It is a type of meme video that long time internet layabouts will recognize the irreverent take on some property, in this case Super Mario Bros. done up in a whimsical yet somewhat profane way. The highlight of the audio, though, comes after the introduction, where performers Group X do a voiced rendition of playing Super Mario Bros., including music and sound effects, back by drum and cymbal (and, later, bass). Being a part of gamer culture from that that you can expect some coarseness (like a crude Flash animation of poop being tossed at a toilet). Some people like that kind of thing I hear, I can’t tell you why.

The attributes of early Flash animation are prominently on display, like copious use of tweens. Flash is still around as an animation tool, and I presume tweening is still available, but with the death of browser-based Flash (not counting Ruffle) recall of the unique crappiness of badly-made shape tweens is rapidly fading from internet memory.

Well, there it is. Hey, it’s Sunday, I’m not supposed to be stressing about posts made today!

“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.

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!

Video: Identifying Luck in Mario Party

We just had a post on a long series of videos about Super Mario 64‘s the A Button Challenge, so why not do another? I’m sure this won’t abuse your willingness to put up with what scientists call “all my crap.”

Mario Party is a series that skill will only carry your so far into. After a certain point, only the favor of The Lady (not Peach or Daisy) can ensure your victory. But, how much of the game is up to the rolling of virtual dice? And to what lengths are people willing to go to find out? Well at it turns out, lengths of over 16 hours:

This series is not yet complete, in that creator ZoomZike has yet to produce one on Mario Party 7, or later games, but the one on Mario Party 6 is over five hours long all by itself! This is truly a level of obsession with which my own petty focii cannot hope to complete.
