You got Coleco & 7800 games? Chances are I want 'em. I don't even have Donkey Kong, Smurfs, or Zaxxon for the Coleco. Or Pole Position II for the 7800. Sad, I know.
I might be willing to buy if the price is right. But I prefer trading.
For trade I have:
GB Nekketsu Dodgeball (complete)
Genesis Madden '93 Champ. Edition (complete)
NES Wally Bear & the No! Gang
NES Power Pad
PSX Final Fantasy VII, original, mint, complete
DC Midway Arcade Hits Vol. 2
Xbox Street Fighter Anniversary Collection, mint complete
Other random stuff, just ask.
