I recently got a BS-X cart in a lot of Super Famicom games which had BS Dr. Mario on the memory card. I've been trying to put a value on it, but haven't been able to find any indication to its worth with the exeption of one German ebay auction which has it listed at €200 (I've looked at several Japanese sites as well, including sold listings on Yahoo auctions). Is there anyone with knowledge and value estimates for BS-X games here who can give me some better value insight?
