CTcert is nothing but a glorified deviceID + signature of the deviceID and issuer.Okay. Who should I ask to get a guaranteed answer?
Maybe if I could find a 3dbrew page on ctrcert.bin I could figure it out myself.
I don't see what makes that illegal, but they ban localFriendCodeSeed_B and it's a kinda similar thing (LFCS+signature).
GBAtemp always leans heavily on the side of "not allowed" because they get so much attention about these things from lawyers etc.
