SuperGrafx © 1989 NEC Home Electronics, Ltd.
The SuperGrafx is a fourth-generation home video game console manufactured by NEC as the successor system to the PC-Engine, released two years prior.
Originally known as the PC-Engine 2 during production stages.
The console was rushed to market, released some months before its initial release date of 1990, only having modest updates to the hardware. With only six retail games released that took advantage of the console's hardware updates, the SuperGrafx was a commercial failure, selling only 75,000 units total in both regions.
