Greetings, everybody!

I started playing Digimon FireRed and it's a hacked rom for GBA.

I want to multiply the amount of EXP received from each battle, maybe for 3x or so.

I found the address that modifies the EXP really received without changing the text message with the EXP amount, so if I freeze this adress with x EXP, I'll always receive this amout after the battle.

After that, I clicked "find out what accesses this address" and the only function that appeared was this (attachment).

So now I don't know what to do because I'm really a begginer and would like some help or tutorials, if any exists specifically for this matter.

Also, as a beginner, I really want to understand and learn how to read assembly so I can start playing with some games, as I am wondering if I should start studying languages to become a developer (in a general sense).

If you can help me or even send me links so I can start learning, I would really appreciate!

Thanks in advance, peace.

You picked a pretty hard project to start off with.

Emulation can work in several ways. GBA emulators usually work via interpretation- basically a computer program reads native ARM instructions, decodes them, and performs the same action that the ARM processor would.

Those instructions are probably accessing many more addresses than just the exp. You could get around this (see step 9 of the CE tutorial- in this case you might compare against a "static" address in the context of the ARM architecture), but most people would target the emulated architecture itself. This is what gameshark codes do.

I don't know how to do that myself. The emulator you use might have tools to help. e.g. an ARM disassembler, maybe a gdb stub, but that stuff certainly wouldn't be beginner-friendly.

Oh, I see.

Gameshark codes are really complex, then?

Guess I'll stick to the freezed exp then! Thanks for the response!
