well, some games (homebrew) dont work on custom firmware if you have your kernel set to 3.xx and try to run them from the "GAME" folder.
your testers probably did that rather than put the game in the "GAME150" folder like they should have done if their kernel was set to 3.xx rather than 1.5.
If you need any testers im always willing to help
(on 3.40oea if that makes any odds)
