Okay, so as we know by now, the US release of Phantasy Star 0 isn't working on any of the M3 branded card (with the possible exception of M3i Zero). There seems to be a hex AP check that strangely only affects M3 users. So I figured it'd be a good idea to start a thread where we could work towards fixing this little problem, so M3 users could get to enjoying the game with the rest of you. Anyway, what we know right now is that the game whitescreens after the first conversation after the opening movie. Then if you turn off the game and reload it, it whitescreens immediately. This seems like an old-school AP check, not anything complicated like say, M&L Bowser's Inside Story. So it shouldn't take too much work to fix. The only hard part is going to be finding the proper bytes that need changed. Anyway, I personally can't really help. I know little about this kind of stuff. I just figured I'd make this thread so those who do know about it can have a place to discuss a fix.
