Maker - Sega   Catalogue No. - G-4503

Type - Network System Cartridge

Those of you that own Japanese Mega Drives may have seen this cartridge pictured on the back of the box.  It all sounds very interesting from the title "Sega Games Library" and even looks pretty interesting from the cover but just what is this cartridge?  Well it has no games on it for a start.  It's used to get your Mega Drive to connect to the special Sega servers.  From there you can do such crap as betting and online banking.  I think that's about it really (-_-)
