The EBOOT signer itself can be signed and it works, so people with OFW can try to sign and test the EBOOT’s they want.
I have mixed the crypter code by “bbtgp” and the unpack-pbp.c and pack-pbp.c from the SDK.
I have named it “PSCRYPTER” though that doesn’t matter really.
ISO Loaders, 6.20 HEN can’t be signed. However many, many homebrew apps & games can. Almost everything else. Try you’ll be surprised at what you can now run on OFW
