Homebrew NitroH4x, but for GBA?

[HAMMARZ]

I was wondering, is there a program like Nitroh4x, but works for Slot 2 games? (Like a legit Pokemon Sapphire cartridge)

For roms yes/kind of (stuff like GBAATM or the older similar apps) but legit carts the best you can do without actual cheating hardware is dump the save and use an emulator to cheat with said save before flashing it back.

Pokemon did have some save editors of a sort but I have no links to hand and cheats are just as easy anyway.

I tried something like this before with something called EEPINATOR (or something like it) and all I got was an unreadable .sav. Then when I tried to put a save file back on the cart, it just wiped the save on the cart. Even when I tried writing back the .sav file that came out.


How would I go about doing this the right way?

yeah, I also got a question.
If you put a R4 in a DS, you can load the (original) GBA card that is in slot-2.
My question is: If I put a real Kingdom Hearts game inside slot-2, is there then a way to use cheats on it without slot-2 flashcard?
Please comment...

anyone???

I believe the answer is no. I think Cheat hardware works by inserting the code into the game as its read so it has to have a chance to intercept the data to run the cheats which would only be possible with an R4 if we used GBA in DS mode which is impossible as we can't emulate GBA in DS mode.

Really? I believe that cheat devices like gameshark modify the RAM of the game. Im sure that's how Action Replay and Game Genie do it.

i think you'd need to run the cheat homebrew in gba mode for it to work... although, ds mode homebrew can chuck a frame around the gba game so it can obviously modify the ram and have it not cleared when swapping to gba mode
maybe an ar-type prog would be possible via ds mode...

 

[fgghjjkll]

wait. when ds mode switches to gba mode, it clears the RAM and downclocks everything to gba and switches to the GBA BIOS. I'm not to sure how the frames work but you can't have AR homebrew running first and then boot a gba game. Unless it patches the codes into the rom and runs it.

Yeah.. what i want is a program on my ds that can patch(and perhaps unpatch) the rom so I can use my 3in1 to play it

To my knowledge, nothing of the sort exists. There are of course various programs on the PC that will apply cheats directly to the rom file, but nothing that runs on the DS itself.
