Yeah, I'd be able to figure it out...If I could get my ROM to work on my No$GBA 2.6.
I've tried patching the ARM7 with DS Lazy, and using the anti-piracy code. I get a Grey screen for about 2 seconds, then it goes to the usual, dreaded, re-insert cartridge screen.
Although now that I think about it, I could use a code that might actually be too challenging for my skill level, even if I could open the ROM and filter through the codes.
I'm now also looking for 2 codes, one for each of Head and Body Armor, that would increase the normal inventory size from 50 to 250 maximum slots for items. Or rather, it's more of a modification to a section of code already in place...I would have to apply it as sort of a direct patch to the game's programming, in a sense. But I strongly get the feeling that this is possible, and it would save a serious headache for someonewhodied if you gave him said codes. (We're kind of working at this, we've been communicating about hacking Nu items on Gamefaqs, until all the related topics were modded.)
Side note, I hate that on Gamefaqs, you not only get a group of ravenous beggars for these items, but a group of self-righteous mods that strikes down AR code topics whenever they're posted. I happen to be one of the people who owns most of them, and is on occasion hounded for these items, which is why I dramatically lowered my daily posting count there.
