When starting a game type in Boba Guri. You must have a space before 
Boba and space before Guri and both names must be capitalized or the 
trick will not work. When playing press start and hold R-Z for a 
character select screen, or R-C (any C button) for a vehicle select 
screen. (When name is typed in also unlocks all levels and a hidden 
option menu.)
