i was too busy with school and work and haven't even touched my wii in like 7 months or so. i can't even remember what cios version i'm using, but i just loaded my usb loader and on the bottom, it says cios249 rev14. i'm reading this forum now and looks like the latest version is rev19??? should i update to rev19? because it seems like games are running fine on my rev14 (although i haven't tried any newest games yet). what's the difference?
