    Well, I recently downloaded the Pokemon Mega Power ROM Hack for Emerald, but whenever I try to patch up the .ups file with a Emerald .gba file, it keeps saying: Failed! Input checksum is invalid. I don't know why this is happening, and I've tried using all the available options on tsukyomi but nothing seems to work! Could anybody please help me? I have tried downloading a bunch of Emerald .gba files of the internet, but nothing seems to work :( Please help me!
