| A very interesting N64 prototype sold on ebay on February 18, 2012 for a staggering $1,358.33 by that time it was a record for an N64 prototype sold on ebay. Tamiya Racing 64 is a proof of concept shown to Nintendo to get approval to go along with development of what would become Looking Glass Studios unreleased "Mini Racers" game.
An awesome piece of N64 history right here.
The ROM on the cart was dumped and released by the new owner and the cartridge then went into the hands of an unknown collector. |
