Nintendo (has more dust in it than a dust bunny), Super, 64
Sega master system, genesis, saturn (barely, need to get a new watch battery for it)
The following i still own, but do not work:
3DO - no, i am not going to re-solder the board and switch chips on it to get the JP games working or the memory controller working
Gameboy - and water don't mix...
Vetrex - umm yeah picture tube monochrome monitor... ><;
Atari 2600 - need to get a new power cord and boar test the connection area (;_;)
Commodore 64 ... I really don't feel like waiting for old style floppy or tape drive reading times and the cartridge games weren't that good compared to atari
Atari lynx ... wow what a waste of money ><; It is the first time i have heard a capacitor "squeal" before.
The following i have owned, but either returned or re-sold
Sega dreamcast - lol sucker...
X-box 360 - sigh.. i can rant here, but i am not going to. People are going to support whatever they "think" is best regardless.
