my copy of mario kart won't play on my wii through sun key lite, i have to use gecko to boot it otherwise i get system files corrupt message. i fitted a sunkey lite to a m8's wii on friday and tried my copy and it worked perfectly, but then he played tiger woods 10 and did an update off the disc and now mario kart comes up with the same error as mine. can i undo the update or patch the game so it will work without soft modding? the other two backups he has play perfect.
btw.. it's a pal console and the update was from a pal tiger woods game

thanks for reading
