I have 2 questions about Nintendo certificate chain ("cert.bin" if extracted from ISO): 1.) Is the cert.bin the same for all games? (My about 60 games share identical certificates) 2.) What happens if I generate a self signed certificate chain and use it instead of the Nintendoa chain? Does the Wii confirm the certificates by using any other source? If the Wii accept a self signed chain, it is possible to create a well signed ISO (and other well signed stuff) with self made keys.
