Good luck converting a CIA back to a 3DS file
There’s a program that claims to do it, but my antivirus found a virus in it. So I deleted it. Makerom doesn’t work, you need a ROM spec file. Don’t know how to create that. Wanted to see if the 3DS emulator works. Guess I won’t, since I have no 3DS files. I delete em after I convert them a CIA file.
