When I won this auction for a Lynx and two games, Toki was not working. It has gross, green corrosion stuff on it so I sanded it off with sand paper, wiped the cartridge down with console cleaner, and it works fine! I also completely disassembled, thoroughly cleaned and reassembled the Lynx so it's much cleaner than it was originally. Unfortunately the screen still has visable scratches all over it, even after I tried removing them with PlastX. Luckily this is just a plastic piece that clips onto the Lynx, so it can be replaced if I find a better condition one.
