I found these Famicom games at a garage sale near my house a few weeks ago for .25 each.
Peach Boy Legend by Hudson Soft (complete)
Tetris by BPS (almost complete, no plastic tray)
Tetris 2 + BomBliss by BPS (no box)
Mahjong by Pony Canyon (complete, box in fair condition, there was also an instruction manual for some Data East golf game in the box.)
Super Mario Bros. by Nintendo (complete, but instruction manual is all chewed up. No plastic tray. The box still has the price sticker! 3,920 yen.)
Jin Sei Geki Joh 2 by Taito (complete, comes in plastic case.)
I haven't tried any of them yet, but the cartridges are all in good condition. Can anyone give me an idea of how valuable any of these are?
