I got one of these bundled with an AGS-101 recently and it seems to work well enough with most of the games I've thrown at it, except for Pokemon Sapphire where the screen goes black when you restore a save state. I have not extensively tested but it seems like this hiccup is recoverable: if I press start and then A the screen appears and you can exit the menu and play normally. (Choosing SAVE in the menu crashes the game, however.) I don't know how the original owner patched this game b/c it was on the miniSD card when I got it. I'm really liking the save anywhere feature which could make a lot of platform games less frustrating when you fail to jump to exactly the right spot, fall off, and have to start the whole level over. I can't find a list of games that definitely can (not) work with Supercard MiniSD. The one linked in the gbatemp review is not there anymore.
