Welcome to Gaia! ::

Why wont you let me use my PS2 codebreaker crying crying crying

Yes.

Latest firmware.

isnt the code breaker one of those things that lets you cheat on games by unlocking a bunch of stuff?

If its not a game alone, there is a lost chance it will recieve emulation.

From what I understand...I think so. I'm not sure what exactly they do, but when you select your codes and start the game, it saves something to the memory card that the game will recognize on boot. Or perhaps saves some executable on the memory card to run in the background while running the game in case of RAM issues...not sure. I can't remember where I read it, I'll have to go find it again.

If you're familiar with homebrew, maybe it's a lot like the independent exploit, where the executable lists the games to execute on when they are booted. Except it's an official type thing, so it works on the slim too?

Anyway, I lost my codebreaker, so I can't test it out sweatdrop

I don't see this as a big possibility unless you're editing outside the game memory. All you're doing is hex editing, and as long as you hex edit the game memory, and nothing else, you shouldn't have problems.
