Edit: So I have to decrypt ROM and convert it with Simple CIA? What's firmware spoofing?
Edit 2: Firmware spoofing allow to play a game with 5.1 on 4.5 (per exemple) but with 9.5 EmuNAND, it's useless...
So please, is it possible to convert a 3dz ROM with a header to cia directly?
And should I trim ROM before convert it?
