NEC CD-ROM 2 (CD-ROM PLAYER CDR-30) NTSC-JAPAN (SANS BOITE NI NOTICE - WITHOUT BOX AND MANUAL)

The PC Engine SuperGrafx (PCエンジンスーパーグラフィックス Pī Shī Enjin SūpāGurafikkusu), also shortened as the SuperGrafx or PC Engine SG, is a video game console by NEC Home Electronics, released exclusively in Japan. It is an upgraded version of the PC Engine, released two years prior. Like the PC Engine, the SuperGrafx was also imported and sold in France.

Originally announced as the PC Engine 2 (PCエンジン2 Pī Shī Enjin Tsū), the machine was purported to be a true 16-bit system with improved graphics and audio capabilities over the original PC Engine. Expected to be released in 1990, the SuperGrafx was rushed to market, debuting several months earlier in late 1989 with only modest improvements over the original PC Engine.

Only six retail games were produced which took advantage of the improved SuperGrafx hardware, and one of them could be played on a regular PC Engine. However, the SuperGrafx is backwards compatible with all PC Engine software in both, HuCard and CD-ROM² format, bringing the compatible software total up to nearly 700. Due to its commercial failure, none of the added hardware enhancements were carried over to the later PC Engine Duo consoles.
