rimsky82's codes

[rimsky82]

Unfortunally, your code also have the same problem as @VisitntX code...

Oh, that stinks. I tried the potion thing, couldn't find it right away. I really thought the code I came up with would work. I'll look at it again later, now that I know which door you're talking about.

@rimsky82, whether is possible you make a "Press Select To Switch Between All Available Characters" (General Hawk, Duke, Road Block, Wet Suit, Storm Shadow and Snake Eyes) and "Don't Lose Any Character After His Life Reached 0 Points" GameGenie codes for NES game "G.I. Joe: The Atlantis Factor"?

This code was requested by Sephiroth. Thanks be to nolberto82 for giving me some incite with the MESS debugger.

Defenders of Oasis (Europe, USA) [gamegear]

No Random Battles
C97-8FC-809

Let me know if you run into some problems.

EDIT: Here is a cheat file I made for MESS for this game. It has the No Random Battles, Inf. Energy, 999,999 Dinar (money), Inf. Items and Have All Items. Thanks again to nolberto82 for helping me learn the subtleties of MESS.

Put the zip file in the same directory as MESS, then add "cheat_gamegear" to your cheat path.

We should make a short guide of how to hack with MESS for the various systems so anyone can have the info at their finger tips.

[rimsky82]

That's a good idea, though I know Pugsy has already written a good guide using MAME, which uses the same debugger.

[Abystus]

I was never able to get the cd-i games to work in mess. Tried different bios, etc..., but was never able to get any of them to get beyond the start up screen. Maybe one day I'll attempt it again when I feel like downloading the iso files for these again. Nice work rimsky.

[rimsky82]

I had that problem too, but they fixed it today if you're able to compile the source from svn.

[rimsky82]

I'm starting to think we should write a good guide on using the mame/mess debugger, even if for myself. I'm having trouble getting it to break on some systems. Abystus, do you have write access to the wiki? You should. http://gamehacking.org/wiki/Main_Page

[Helder]

I had the same issues too but it ended up being that a RAM break would be "wp adresss,1,W/R" and on a Rom address it was "bp address" .

[rimsky82]

I know the difference between watchpoints and breakpoints, but I couldn't get the debugger to break with watchpoints on tg16 or segacd.

[Abystus]

From my discussions with Nolberto about tg16 memory, he stated that you subtract $2000 from the ram address listed in the search results, then set a watchpoint on the new address. As for Sega CD, it may follow the same rules that apply to Genesis if the search results are returned in a E0 format instead of beginning with FF (more information on this here).

Also, I appear to have write access to the Wiki (responding to your previous post). Possibly we can get a few pages going that give detail on how to break on particular systems (formulas), along with other information about the commands and general setup.

[Helder]

Would be a great asset to have such info, also the ram searching would be nice to include on how to get it going and if possible to edit RAM on the fly. I know you can edit the ROM values but I have been unable to edit the RAM, this is generally on the Genesis as I have not tried other systems in MESS.
