I recently dug some of my Nintendo stuff out of a box after a house move, which has started a chain recation of me finding all of my Nintendo gear and using it once again. I only have the recent systems (DS Lite and newer) with the exception of a grubby GameBoy.
I used to have a N64 with controllers and games, but I traded it for a "working" Xbox 360, which broke 10 minutes after being used. I'm still gutted about it (4 years ago) and I know the guy who has it, but I don't think I'll get it back.
I'm after anything older than the DS Lite, so I guess that would mean GameCube, GBA, N64, VirtualBoy (I wish) etc.
If you have anything you'd be willing to part with, please PM me with details! Thanks!
