I own:
Super Famicom (Japanese)
Nintendo 64 (Japanese)
GameCube (Japanese)
Wii (North American)
DS (North American)
DSi (Japanese)
PlayStation (Japanese)
PlayStation1 (Japanese, and yes, PS and PS1 are different)
GameBoy Advance SP (North American)
Interestingly, DS games don't have a region code, unlike Wii and GameCube games. (i.e. you can play American DS games on a Japanese DS or vice versa)
^We don't need pointless shitposting like this. If you don't have anything to say, just don't say it.
As for the topic, I have pretty much every Nintendo consoles from the SNES to the Wii (plus an old Game & Watch) except for the Virtual Boy and the 64DD , a Dreamcast, a Xbox, a PSP and a crappy Tiger lCD game (if you count those as consoles).
