I still have mine somewhere. I traded in a ton of great games that I really regret not having now (Guardian Heroes, Radiant Silvergun, Die Hard Arcade, Megaman 8, Sengoku Ace)
Still have a few that are worth something (Panzer Dragoon Saga, Burning Rangers, Psychic Assassin Taromaru). A lot of my collection was ports of fighting games that you can now get easily on MAME.
Last time I dug mine out I had a tough time getting the import cartridge working and only my Nights controller was working 100%.
