the red eye - bootleg nes heaven.

One of the best NES-related websites anywhere is the wonderful TheRedEye.Net, which deals with unreleased, pirate, and just plain messed-up bootleg Nintendo carts. Most of the good and crazed bootleg stuff is found in the (NES nudity ahoy!) release archive, including classics from a bizarrely cultish Asian company called Sachen. And the horribly hacked version of classic fighters like 'Street Fighter 2' or 'Mortal Kombat' are genius. :)
