This is all good info. I'm much a newbie when it comes to the whole IOS/cIOS scene .. initially, I didn't even know what they meant. I've been burning backups and playing them on my D2CKey'd Wii for a while now, no problems. Luckily, I'm still at 4.1 and only recently had my first real issue with the New Super Mario Bros. game. Just learning about patching that all up to run.
Good I say! I've been getting bored with crap working 100% all of the time! lol. I haven't needed to read up on anything for a while and didn't even realize there's a USB loader out now ... that's pretty friggen cool so I'll be looking into that. How deep do I want to go? well ... only time will tell!
