Released September 2005 for $59.99 Generation NEX is a Nintendo Entertainment System (NES) hardware clone released in 2005. It is developed by a company called Messiah Entertainment, Inc. with the name being a portmanteau of Generation X and Nintendo Entertainment System. The machine is designed to play most games released for the Nintendo Famicom and its American/European equivalent, the Nintendo Entertainment System. The console takes both the Japanese Famicom 60-pin and North American/European NES 72-pin cartridges used by Nintendo.
Messiah Entertainment, Inc.'s official compatibility list states that the system is compatible with 97.25% of NES games released in the US. Twenty-one NES games are listed as not compatible, including Castlevania III. The compatibility, with regards to games that Messiah's compatibility chart lists as working, is disputed; while there are claims from some that the NEX is faithful to the original Nintendo Entertainment System, others claim that the color and sound reproductions are inaccurate and some games have additional glitches when played on the NEX.
