Hello, I followed this guide ( https://gbatemp.net/threads/release-agb_firm-signature-patcher-gba-rom-converter.390313/ ) on building .cias in hopes of porting a modified version of Pokemon Fire Red to the 3DS. This hack specifically. ( https://www.pokecommunity.com/showthread.php?t=285094 ) After I built the .cia, I installed it with FBI, and it seemed to work fine. I tested to see if I could save and it gave me an error saying it was unable to save. Does anyone know what might have caused this? Thank you.
