EverDrive GG X7

I got one of these and it has worked flawlessly for a few years now and comes highly recommended for playing prototypes.

Bought one of these a while ago. It's an awesome bit of kit, really brings the Game Gear experience up to date. Very reliable and well designed as you would expect. Thought the above reviewer was very unfair knocking 2 stars off for lack of an SD hole which is mentioned in the description.

I own this card too, it's fantastic, no need to carry a bag with tons of games with it and i also don't need that clunky adaptor to play sms games on it, my only complain is theres no hole for the sd card so i,ve cut a hole into it to get direct acces to the sd card so i don't need to have open it up constandly for installing more games on it.
