Name and shame - 100% working and no diodes? I don't think so! The man who sold you this is a scam artist, no ifs or buts.

I've bought a few games and one I risked sight unseen (an expensive monster bash imported from Germanycto the U.K.!) the monster bash was the best one I bought but did have a problem with ththe drag motor -

Even when you see a game it's not hard for a seller to "patch" it up so it's working ok but is on its knees! You want to avoid that hassle buy NIB - that's why I love the remakes as it takes the agro out of buying a MM or AFM.
