Hey, I'm new here. I recently hacked a few GB ROMs, and an Emulator. They would work fine, but I just relized I don't have the right version. I have version 1.81, and I need 1.50, or (I think) 3.50. I need a software capable of downgrading it to something that will work, and I need a brief rundown on how to do it. (In english, I'm not too much of a cpu nerd, just a newbie.) .::Thanks in Advance!::.
