Switching from Gateway to CFW can be a pain, especially since all your saves were created on Gateway. There's only one way to get those saves to be usable on cia games, and that's to decrypt the saves and eventually import them in the end. It's a very tedious process, but worth it in the end to be able to keep all your saves you worked hard on for so long. Gateway has become more and more obsolete, with CFW being more convenient to work with. ESPECIALLY Arm9loaderhax!...
