I’ve been trying to download Fire Emblem Storge, I click on the link and download it but when I try to play it on my GBA Emu it won’t let me. Any idea why?
Distributing ROMs, prepatched or not, is not permitted on FEU, so the link only provides the patch. You’ll have to track down a ROM to patch yourself, I’m afraid. Instructions for which ROM file to use and how to apply the patch should be present in either the original post or a readme file included with the download.
EDIT: Looks like the patch is in .ups format. For that, you’ll want to patch using either upset or NUPS. Both should be pretty straightforward to use. Have fun!
