I have about 60 boxed Master System games that I have to trade either as a complete set or individually. The list of games can be found at:
http://gametz.com/user/RipX.html
I also have some loose carts if people are interested too.
For details of any trade or to offer a trade for other Master System games/stuff then drop me a line at:
dymos at mastersystem dot org <- Change to proper email address!!
P.S. I'm in the UK so take that into account if you want to trade from abroad, be prepared to pay the shipping difference.
