dude, I'm interested. I want to see that booklet
Off the top of my head, I have doubles of:
Nectaris HuCard: excellent condition, complete.... well, it is probably missing the registration card).
Final Zone II (take your pick, Japanese or U.S. version). Case,manual,CD.
wonderboy III: Monster Lair (Japanese). Case,manual,CD.
A bunch of sports games (You probably wouldn't be interested in sports games... mostly baseball (i.e. power league)).
I don't know what these games go for, or Gradius, so I'm willing to combine stuff.
I'd have to actually look at my HuCards to see what else I'd trade. I'm assuming it's only Japanese HuCards you're interested in?
