ROM Hackers Sans Frontiéres

Alright, sorry about that bullshit before. What happened was I was dumb and was comparing the wrong version of unmodified SFII Champion Edition to Rainbow Edition (henceforth abbreviated as RB). This research will be based off a hex comparison of the program roms from romsets sf2ceja and sf2rb. I am...

Zero800 did an amazing job on this hack. He also used my Gecko Grabber tool for all the new graphics he added! He finally broke the curse of Street Fighter II arcade hacks being a bunch of chaotic nonsense.

*this post contained wrong information due to a dumb mistake I made and a corrective post is forthcoming*

Sorry, it's against our policy to help anyone who donates money to RHDN.

Fucking hot!

ooooooohhhh yeeeaaaaahhhhhh boyyyiiiiii

$0A5868 = Balrog Sprite $0A5468 = M.Bison Sprite Those are the only ones I have in my notes other than Vega. Here's how you can track the rest of them down, though. In MAME press F4 to bring up the graphics viewer. By default it should bring up the palette screen which displays palettes that are cur...

Many arcade games from the 80's to the 90's used a 68000 as their main CPU, but depending on what era of "arcade" we're talking about, many others were used as well, such as Z80, 6502, M6809, etc

This suggests one of two things - either the hacker spent the time to create a working disassembly of Final Fight, or there was a serious leak from Capcom. Do you thing that the creator of this hack was one of the creators of the original game? Or a dumpster diver. It's a question for the ages.

Yeah, there's a lot of work to be done to make it playable before I can even think about reworking the sprite system. I was trying to prioritize working on things that were critical to the overall 2 player experience before worrying about cosmetic stuff. The top priorities right now are allowing ene...

I've thought about a couple ways of doing the character select screen without having to resize the portraits too drastically. The challenge is that Cody's portrait uses a few different palettes to get all the detail in his clothes, so his tiles have to line up a certain way.

It was last updated a couple years ago. I haven't given up on it, but I've been busy with arcade hacking. I do want to revisit the 2 player SNES hack one day, just not sure when.

I'm Rotwang. The hack was on here but it got accidentally deleted a while ago. Here it is again:

The code is not similar between the two games at all. They share the same alphabet tiles but they are otherwise two completely different programs with different kinds of data. You would have to reprogram every enemy and boss from the ground up along with redoing their animation data, every effect en...

Cool, looks like the first Diablo but with space marines

I want to examine the title screen and character select screen a bit more (so far I've determined that all of the walking characters on the title & charsel screens are enemy entities) but to satisfy my immediate curiosity I jumped ahead to the player handler. Final Fight's entity state machine uses ...

The start of attract mode, $402, is mostly the same between ffight and ffightjh, but with a couple inconsequential differences. In ffight's code, address $444 is move.l #$1F, D0 However, in ffightjh, it has become moveq #$1F, D0 What's the difference here? Well, the exact same end result is achieved...

There is a hack for CPS Final Fight that has been known on the internet since at least as far back as 2009. It changes a number of things about the game, but most notably it expands upon character selection and allows you to play as a handful of the game's enemies. The hack goes by a few different n...

Sick dude! Have fun, let me know how it goes. Gecko Grabber is the result of sheer tyranny of willpower to hack CPS games. I'm not a trained programmer, so my solution to the problem isn't the most elegant. PCX format was chosen because it preserves indexed color data, while a bitmap does not. Too m...

Hi again, and many thanks for the palette guides. I have made the first sprite (stop) using the exported .pcx in photoshop, and after that loading it in Paintshop Pro for exporting it in Version 2 format. I have one problem here. https://i.imgur.com/i1ZnpXy.png The program says that cannot accept p...

You're welcome! Here are some more Rom Mangler configs. Come on everyone, fucking hack some CPS games with us! Street Fighter II: Hyper Fighting sf2hf_split_gfx.cfg ROMX_LOAD_WORD_SKIP_6,s92-1m.3a,000000,80000 ROMX_LOAD_WORD_SKIP_6,s92-3m.5a,000002,80000 ROMX_LOAD_WORD_SKIP_6,s92-2m.4a,000004,80000 ...

Alright, here's a quick and dirty guide to hacking Willow using Gecko Grabber and Rom Mangler. Click here to get the new version. You will need Java runtimes installed for this to work. Make a new folder called WillowHack and extract the contents of willow.zip to it. Extract RomMangler.jar here too....

There is a tool called Rom Mangler that grego2d wrote for splitting and merging MAME ROMs. I just tried making it merge Willow's graphics ROMs, but it seems to not like the way some of the ROMs are mapped. This will be looked into, sorry I don't have a good answer for you right now. But I might as w...

Now that the forums have reopened, it's time for me to flood them with threads on all my various projects, the vast majority of which are Final Fight related. So, let's get this big one out of the way! Early in 2019, when these forums were first opened, I had a thread about my 2 player hack for SNES...
