nah no need for worries as those people havent tried out the DSTT themselves to they are just prob being abit snotty to shelfs themselfs as super experts but it works fine as i have one myself and it works 100% if you do everything ok and jus dont damage it then your DSTT will just stay alive an function well an normal.

nope you dont have to rename them as long as the ".nds" is at the end of any game name for example mario kart just have the ".nds" at the end of the name so the DSTT can read it, u can rename a game to anything u like as long as ".nds" is at the end of it like this "Mario Kart.nds" and thats all :)
