I've updated my firmware on my DSTT sdcard, then put the latest version of YSmenu on it. I can play ALL of the games I have such as, Pokemon Heart Gold, Soul Silver, Ranger, Conquest, etc. except for Pokemon Black or White. It gives me "disk errcode=-83" then asks me to restart the system. I've been trying to find various ways of fixing it, like patched version of the rom, clean versions, etc., but so far no luck. Any help would be greatly appreciated.
