I added the valid Croc passwords to the wiki (based on blind faith for now, I will get round to checking at some point soon) with a credit from this forum post. Happy to change it once its on twitter or the blog of course. Curiously 2-1 and 5-5 match the psx codes but 3-1 and 4-1 do not. Croc: Legend of the Gobbos/Hidden content - Sega Retro EDIT - all four passwords work on the US version (I only check they load the level they're supposed to, not for any other effects)
Thought I'd have a look into this - the ST quote comes from Fergus McGovern, top dawg of Probe who is infamous for having his head stuck in a dozen titles. I honestly don't know if he's correct, however I am pretty sure the two ports of Bubble Bobble and Rainbow Islands are entirely separate products which Probe were forced to jam together. Bubble Bobble was ported by Probe, but Rainbow Islands was ported by Graftgold - both games show a credits screen if you wait long enough on their titles. Graftgold were responsible for porting Rainbow Islands to the Amiga and Atari ST in 1988/89 - there are even some shared staff, however I don't think this is ST code running on a Saturn. I think it was written in C... because if you have a look at the CD-ROM, "2.BIN" contains hoards of uncompiled C code: Code (Text): void Refresh(void) { ScreenModeInfo *Scr = SCREEN(USBuffer); if (NewLook==0) { memcpy(Scr->Address,(WorkMem->Address)+(MasterY *320),320*224);

But what about Bubble Bobble? That's a bit harder to know for sure - I think the entire game lives in a file called "3.BIN" - everything else on the disc is either Rainbow Islands or the menus. What I do know is... it doesn't look like the ST port. But it's also not a perfect arcade conversion: The ST conversion is credited to Software Creations for Firebird - I don't think there's any relation at all other than "they're both ports of Bubble Bobble". But maybe Probe were developing a version of Bubble Bobble independently that got put on a shelf for a few years, idk. I suspect the Saturn version was ported from the PlayStation though don't quote me on that. tl;dr it's all a bit weird
Could be that they used the ST code as a reference for in-game logic rather than a direct port which wouldn't make alot of sense given how different the architectures are.
I added screenshots to Saturn Bomberman Fight!!/Hidden content.

If you're still looking for cute mascot platformers to throw your disassembler at @Bo102010, here's a good mystery. Cheat sites list a whole bunch of codes for Rayman, but when we tested them all, we could only get one to work. Maybe it's another Croc where the Saturn has a cut down set of codes?
It's possible... From what I recall, accurate emulation of the arcade game wasn't even possible until the protection MCU was decapped some time in the mid-2000s, due to the game logic running directly through it. Prior to that, Emulated Bubble Bobble played wrong... Yeah, I know, we're talking ports here rather than emulation, but the fact that game behaviour back then would've been entirely down to eyeballing rather than reverse-engineering, maybe they went back to the work of a team that had already done the lion's share. *does quick google search* - Here we go: When it comes to Graftgold's ports of Rainbow Islands, Taito gave them every piece of material they ever needed for a 1:1 recreation when they were making the ST/Amiga ports. There were articles in magazines at the time, about the unprecedented partnership between Taito and Ocean that had never really happened with licensees in the past, where they were giving them design docs and original graphics discs. A lot of Ocean's later Taito ports are *very* accurate to the originals because of this.
According to this, Taito gave them the graphics and design docs but not the source code! Their versions have the secret islands because one of the devs was good enough at the arcade game to actually unlock them (and the mapping was done by watching video of the guy playing and pausing it to sketch the maps). I love the UK 8 bit Micro scene, it was just the wild west, you can't imagine it these days. They did a hell of a job given those circumstances! Rainbow Islands | The Beginning (uridiumauthor.blogspot.com) EDIT - I misread and got it backwards, the 8 bit versions don't have the secret islands, they were only discovered by playing the arcade game during development and they weren't able to get them in!
While you're on a cheat code hunt, it might be good for you to go through this: Getting Bean in Virtua Striker games. https://forums.sonicretro.org/index.php?threads/bean-the-dynamite-in-virtua-striker-2.36524/ There's an idea of what you actually need (50 wins), but might be good to check Arcade, Dreamcast etc versions and see if Bean still exists in them all. It'd also be great if you can find any way to hack a save file so this can occur without people having to wing 50 damn games as one team :P
Interesting, an easter egg cameo appearance that only triggers after the machine has been used for a long while isn't unheard of. As you say though, it'd have to be a hack, no one in their right mind is winning 50 games in a row for real. Super model is now a really solid emulator, which makes it a bit more plausible to investigate. Here's a cheat table for 'always 99 goals' for someone to grind through if they particularly want to (untested) Supermodel Forum • View topic - Model 3 cheat database! (supermodel3.com) EDIT - ended up doing it myself in cheat engine rather than artmoney which I've never used before. I'll leave it to win a bunch of 1 minute game tournaments for a bit and see what happens :-) EDIT 2 - should have seen this coming, when you win a tournament it's supposed to do a bunch of replays of the 'winning goal' of each match over the credits. Except I have no winning goal so it crashes :-D. Oh well.
If we're tackling Model 3 mysteries that one would be nice. Virtua Striker 2 is annoying because there are a bazillion revisions: Virtua Striker 2 Virtua Striker 2 Version '98 Virtua Striker 2 Version '99 Virtua Striker 2 Ver. 2000 Virtua Striker 2 Ver. 2000.1 and there are genuine differences between them all. So if it's a case of having them all win 50 games then managing to get one of the secret teams to make a substitution... yeah. This is one where you really need to hack the game - if Bean is a subtitute... well teams usually have more than one sub. Ideally we'd want to have a list (and screenshots?) of the full team... which tbh we'd need anyway even if they weren't fun secret characters. Case in point: FC Sega is made up of Sega developers. So there could be real people in there that you essentially never see. And then we have the revisions that remove and/or replace teams - do these older teams still exist? Mind you, could be worse. Fighters Megamix infamously unlocks the AM2 palm tree after 84 hours of play* - were this an arcade game, it's not inconceivable that a new player would arrive on a machine that had already exceeded this play time. Thus the palm tree wouldn't be "hidden" (and at popular venues, it might be rare to see the game in a pre-84 hour state). *fun fact: I never confirmed this. Because even with emulation, simulating 84 hours is... unpleasant.
Indeed, I was gonna try it once on vf2 (and even that is US step 2, there's a Japan step 1.5 which might be a better choice) and be done with it! But the crash thing makes it a pain to automate so probably not. I'll leave it to future reverse engineers instead.
Hoo boy, this was a rabbit hole. The button handling code in Rayman is actually insane. Most games store button presses in a 16-bit field of flags have something like a buffer of recent inputs that they compare to a list of valid bit patterns. Rayman uses a 16-bit field of flags for button presses, but it turns around and maps each button's pattern to a numerical value: 00 is up, 01 is down, etc. Then it uses the mapping for your first button press to decide which code to track, and from there says how many buttons need to be held for each part of the code. I'll write up the technical details eventually... Anyway, here is the set of codes that do something legible: 5 lives: B, X, B, Z, LT+RT+Down+B 99 Lives: Up, X+B+Z, LT, RT, LT, RT, Up+Y 10 continues: Left, A+C, RT+LT+Z, X+Z+Up 20 lives: A, Right+B, Down+Left+RT, Y+C+Z Full health: RT, Down, Left, Up, Right, B+C, LT+RT You have to put the multi-button ones in as shown. Like you have to hold LT, then RT, then Down, then B. There are three others that the game recognizes: Unknown 1: LT, X, A, X, LT, Down Unknown 2: Right, A+Z+X, Y+B+RT, LT+X+C, Left+A+B+C, Right Unknown 3: C, Right+A, Z+Left+C, X I don't know what they do! Are there any Rayman experts who can try them and see? My actual guess is that they don't do anything. You can set a break point for 0601304e to see if you've entered them correctly, since you may not be able to tell otherwise.
Crikey, that's lightning fast work, well done! Pinging @BSonirachi and @Chimes who expressed interest in this back in 2022(!). This is basically new knowledge, although there's stuff like this list, where the codes sort of resemble the 5 understood correct ones (and have the correct descriptions) but there's mistakes in all of them which explains why they never worked for anyone. Rayman Cheats, codes, hints, tips, tricks (Sega Saturn) (consoledatabase.com) Does anyone know whether there's a Rayman discord or fansite or something we can toss these over to? Bet unknown 2 does something cool will all those buttons.
@RibShark yo peep this one There indeed is. There's the RayWiki and the Rayman Pirate Community, and both of them have discords. I'll hand some of the info to the RPC
Actually did some proper digging. He's not. Amiga/ST Bubble Bobble was programmed by David Broadhurst, who just so happened to also work on the Saturn/PS1 versions. https://www.lemonamiga.com/interviews/david_broadhurst/ According to this interview, the Amiga/ST version was made by eyeing up an arcade cabinet, whereas Taito provided some actual documentation for the Saturn/PS1 versions. So I guess any quirks in the Saturn version should be entirely separate to the older computer ports.
A real 8-bit home computers dream team, Bubble Bobble by Software Creations and Rainbow Islands by Graftgold. Neat.
Some good Rayman stuff in @Bo102010 's twitter at the moment, the three unknown codes appear to be disabled but had functionality in a prototype. The proto even came with a paper guide to the codes (which have different button combos compared to release). I'll hold fire on adding to the wiki until it all shakes out! Bo (Low Context Burning Rangers) on X
Ah, um, yes, okay. Rayman (prototype; 1995-07-20) was dumped back in 2015 and actually came with a piece of paper with codes on it. And that image is included in the RAR mirrored on Hidden Palace. Oop. I'm surprised this hasn't been covered in more obvious detail. Granted it's a port of an then-already finished Jaguar game, but the series is pretty popular online, and all the versions of Rayman differ slightly.
Ooooh ooh I understand now - it's because the details aren't obvious. I spent about five minutes with the prototype - there's a lot of differences in the initial presentation, but when you get into game... it's incredibly similar to the final. Which in turn will be incredibly similar to the Jaguar version. And while I appreciate Rayman 1, I've always found it a bit of a "slow" game compared to... well pretty much any Rayman release since. I'm not sure I want to be sitting down with all the different versions to see how close this Saturn prototype is to any of them, especially if the bigger differences turn out to be in the latter half. One point of note though: this prototype is missing the initial FMV when you start a game. It's instead a slideshow... with a Japanese voiceover. It may be worth checking, if you haven't already, that the GameFAQs codes don't work in the final Japanese version, if it turns out that one was finished first.
I confirmed a few things by comparing the prototype code to to the final version code: The functions that implement the cheats appear in the same order in both versions The three extra ones in the prototype correspond to the three that jump to the same place in the final The button presses are easier to execute in the prototype because they're all single-button, and correspondingly, the code in the prototype is much simpler The functions to implement the missing three codes in the final are just totally gone; they're not present-but-unused In any case, we know some new AR codes for Rayman now.
