Mods
Stereo NES
If you are only getting one mod, this is the one to get! The standard NES audio is upgraded to true stereo output. It is a nice update for the original NES, and also enables you to use stereo A/V cables without adapters to connect the NES to your television or stereo.
Additional Famicom Audio
As an additional upgrade, the stereo audio can be further enhanced to support additional Famicom audio. You will only hear this audio on Japanese games, and is for the more obsessive fan. Requires either converted Famicom to NES cartridges or a Powerpak.
Replacement LED
Tired of your boring red LED power light? Upgrade to a high output red, blue, green or yellow LED.
Light Up Controller Logos
Standard official NES controllers, modified so that the Nintendo logo glows red when the power is turned on. A nice finishing touch to a modified NES.
