all this stuff is likely related to the cios. that's why gamecube games probably work, since it doesn't use a cios. need a syscheck to know for sure. btw, beta 53 can use either port, but beta 52 (the recommended version) can only use port 0. the reason it's recommended is that it can play wiiware games. I think that's related to the FAT library, which beta 53 doesn't use.
