GBA Rom Hacks x EZ-Flash Omega Error?

I'm noticing that a number of popular gba hacks don't work on the EZ-Flash Omega. This includes colors hacks for all the Super Mario Advance Games, Doom I/II, & Donkey Country. Am the only one getting an "Error 4" message when trying to boot theses games up? Am I doing something wrong? They seem to work perfectly on emulators




EDIT: Lmao, now my entire Save Folder got corrupted from trying to run these games. Ugh.
