I have the NES, SNES, and 64 though the only one that really gets played is the SNES because my g/f plays A Link To The Past on it...or did until I got it on the Wii because the SNES version sometimes deleted her game. I want to get the original Gameboy, Gameboy color...and then that would just about complete my Nintendo Collection.
i have a pretty substantial collection nowadays although its less than it used to be
4 snes (1 boxed)
4 megadrives
amiga cd32
spectrum 48k
amiga 500
amiga 1200
nes
n64 (mint boxed)
ps
ps2
gameboy
GB colour...and GB advance
gamegear
dreamcast (boxed mint)
binatone 1
3 nintendo game and watch
2 master systems
as for games...hundreds and hundred
choicest of them would be
zelda 2 gold cart
oot gold cart
majoras mask gold cart
metal gear solid (nes version)
mint boxed perfect dark
mint boxed golden eye
shenmue 1 + 2
