Just three year ago, a new prototype game for the NES was sold on Ebay for the "small" amount of $2700.  This game was Chuck Yeager's Fighter Combat.  This game is a flight simulator but the significant part of it is that Check Yeager was the first pilot to break the sound barrier.  The game has Mr. Yeager's digitized voice and some pretty nice graphics.

A run of 150 cartridges will be sold so gamers can experience this title on their NES consoles.  For those who don't want or can't spend the money on the cart release, the ROM will be released after the run.  The cart release includes:

• 1, Chuck Yeager's Fighter Combat Nintendo Entertainment System Game cartridge (Green), hand numbered ____/150
• 1, Chuck Yeager's Fighter Combat BitBox case with Artwork, hand numbered ____/150
• 1, Chuck Yeager Wingman pin (included in your flat rate box)
• 1, Surprise insert with your favorite Brigadier General!
