Or do I have to use a specialized trimmer for each type of rom? Just wondering because it would be a pain to have to hunt down and use multiple trimmers on the PC when the only reason I need to trim them is for the DS (PC emulators playing from zipped roms FTW!) so doing it straight from the DS would be perfect. At the very least I'd like confirmation on whether or not it works for GBA roms since those would be the bulk of my non DS roms for my AK2. Thanks in advance!
