Dreamcast Code Hacking

[VirusPunk]

Since no one obviously bothered to answer my question on Bioflames 3 weeks ago, I'll see if I have better luck here. Does anyone here know anything about Dreamcast code hacking & such? The Code Breaker website doesn't seem to care about the Dreamcast anymore, so no support from them either. I wanted to know if anyone here knows of any tools/programs to use for finding codes for Dreamcast games. No one has bothered to even make any new codes for RE3, so I thought I would give it a shot. It would be greatly appreciated.

Well, i don't know anything about hacking games on the consoles, But i have tried out a bit with emulators. Using nullDC and ArtMoney, i was able to do some things with the game "Blue Stinger" such as change the amount of money i had. I think emulators are best to use when trying to modify a games memory (Save states! ^^).
For some emulators (other platforms), there is sometimes a plugin or built in function that accepts codebreaker codes. Tho i don't think there is one with Dreamcast right now. (PCSX2, PS2 emulator, has an interesting patch system and i once read some documents on how to convert a codebreaker code into useful information for the patches... Still can't get FFX-2 Debug menus to work yet tho >.>... Tho that has nothing to do with Dreamcast O.O~!).

He means how do you create custom codes via Code Breaker,Gameshark or Action Replay for the Dreamcast version of Resident Evil 3. I too would actually like to know this myself. I don't care much for emulators only for consoles I don't have access to or can afford.

Hmm, well i know that CB/GS/AR have there own formats or encrypt there codes. I found a app that can encrypt/decrypt AR/GS codes for Dreamcast but i think what you do is use a disassembler for the dreamcast executables. I feel as tho im too much of a newbie to know how to do anything other than use memory editors and "hints"(like do any action in game and look for a change in the memory) to tweak with the game.

Would you mind sharing that DC encrypt/decrypt program? Well I was hoping DC hacking was the same as hacking a PS2/PSX game (i.e. elf, memory dump) but I highly doubt it. I can try using Tsearch or Cheat Engine on the emulator then see if I can covert the raw data to GS/AR format using that program, only if you plan on giving out a download link though.

Also tried modding RE3 by creating a modded CDI image, swapped a few enemies around. Unfortunately it wouldn't boot up past the Sega logo.

While doing a quick search i saw some links pointing to a dreamcast disassembler but got nothing but dead links.

Thank you for sharing the link. Sounds pretty interesting though, at least I now know a Dreamcast disassembler exists.

EDIT:

OK I found a site that contains quite a few debuggers and disassemblers for Dreamcast.

You'll need Win RAR to unzip these.

Now to begin code hacking.

Thanks for the help Orin. Too bad there doesn't seem to be any guides on how to do this
