(Windows)[There's another REALLY old topic on here about this but it doesn't work AT ALL.] --I am aware that there is "GAMEBOY ADX" but I cannot find where that emulator saves the ".sav" files so for people like me who play the same save files on your ipod and sometimes your comp, this doesn't work. Plus the in-game save does work for "GAMEBOY ADX."-- Okay, since ALMOST every emulator is broken for the 4.2.1 jailbreak and up.. it sucked. (GPSPhone and PSX4All still worked though.) I really wanted to play GBC games on the go. So, I kept searching and searching how to convert GBC games to GBA files. I tried this "Goomba" program and it converted the game successfully, kinda, but it would only work on my PC emulator, not the iPod one and it wouldn't save no matter what I did. Well, after another nights worth of searching, I found this program called "PocketGBtoGBA." (I will attach a download link because it was a pain in the ass to find.) This converts the game successfully. You do not need to mess with ANYTHING after the first screen, just keep pressing next, it will give you a warning saying it might not work because the file you are using is GBC and not GB, but ignore it, keep going and it will work. Now, with this final game... It will add a yellow color to anywhere that used to be white. But it's not an ugly yellow, its a nice soft one and I was easily able to get past it. The game runs fine on my "Visual Boy Advance" emulator on my PC, and it also works and saves fine on GPSPhone on iOS 4.2.1 on my iPod Touch 4th Gen. (Don't see why it shouldn't for for every other iOS and iDevice though.) I've only tried a few games so far. WORKING: Pokemon Yellow (Default in game save works fine for PC and iPod) NOT WORKING: Pokemon Silver (Runs on Visual Boy Advance AND GPSPhone, but doesn't save.) Pokemon Gold (Runs on Visual Boy Advance AND GPSPhone, but doesn't save.) Pokemon Crystal (Not compatible error) --- If anyone can get the Johto games working, that would be great. I haven't tried any other Kanto games yet, but at least we know Yellow works. ...Yay!
