I have a NES, SNES, N64, Cube, Wii, PS2, Sega Mater System, and Genesis for home consoles.
GB, GBC, GBA, DS phat, and DSlite for handhelds. All consoles/handhelds work too!
Master System is probably my rarest console, Original grey gameboy is probably the rarest handheld, and I have a slew of games for all the systems. You can see them all in my collection. I'm sure there's some rare ones in there. The Legend of Zelda: Link's Awakening for original GB is probably the rarest.
