Consider PXIDEV for NCCH header dumping #11

Open neobrain opened 8 years ago

neobrain commented 8 years ago

If we have access to PXIDEV:ReadCTRCARD_Cmd40, we might be able to dump the raw cartridge even from userspace (assuming that the unknown 0x10 bytes are a raw cart command like Normmatt suggested). The largest part of the dump would still be encrypted, but the (unencrypted) NCCH header could be extracted.

Could this allow dumping of encrypted NCCH header? (And therefore 1:1 cart dumps)?

neobrain commented 8 years ago

Yes, but chances are this command is not accessible from any userland application.

Most games have access to pxi:dev.
