well i still cant get to the main menu...i did the dvd9 update, got the duplicate channels(i hadnt tried the dvd5 yet or ever put any other japanese game in)
it loads up to a screen with two options, then goes to another one that says wifi...hit the left most option on both screens then it booted to the home screen
So that means if you let it make duplicate channels, you don't need to do the swap thing to make it work. Nice
