PC Engine Emulators
The PC Engine/Turbo Grafx-16 was a 16 bit console system released in 1997 in Japan, and it was released in the U.S.A. two years later. It was the first 16 bit video game console system released anywhere, but it did use a 8 bit processor. It wasn’t really a 16 bit system, but the graphics processor was 16 bits. This system initially came out with hucards which was similar to Segas cartridge format. The card was small enough to fit in your wallet. Later, CD-ROM support came out for the PC-Engine/Turbografx-16, and these games were much better. You had full motion video in the CD-ROM games, and interactive movie type games were released for it.
I made a few tutorial videos about PC Engine emulators.
