Will give it a go right now, then. Thank you for the quick reply, this ROM hack is going to be fun to play :D
Edit : Via that method, is there any way I can still randomize the ROM hack?
Okay, just installed CFW/FBI/everything on 3ds.guide yesterday, found this hack. Dumped my US Sun cart ( the dump+decrypt option) via Hourglass9, tested the ROM to be decrypted via Citra ( worked fine) and proceeded to follow instructions to get it on CFW. Installed new CIA via FBI, system...
