Error 10 is “System Files Not Found!” As it very helpfully tells you. However, I’ve personally found that it also can mean it doesn’t like your SD Card. i have an SD Card that refuses to work with my Everdrive. So just make sure you placed the EDFC folder on the SD Card, and if that doesn’t work see if you can try a different SD Card.
That is called a "line of 1s lag frame". I assume you can guess why.
WiiVC I take it? I don’t see why not, it’s better than some other things on the boards (no offense to anybody, I’m guilty of it myself)
When I first started running SMB1 a year and a half ago and was just messing around with AISSON, I never thought I’d get a sub 5, much less be the hundredth person to do it. Its amazing how much fun this game has been for me.
