openMSX is an emulator for the MSX home computer system. Its goal is to emulate all aspects of the MSX with 100% accuracy: perfection in emulation.
MSX is an old Z80-based family of home computers which appeared in autumn 1983 as an attempt to establish a single standard in home computing similar to VHS in video. They were popular in Asian (Korea, Japan) and South American (Brazil, Chile) countries as well as in Europe (Netherlands, France, Spain, Finland) and former Soviet Union, but they are virtually unknown in USA. Although the MSX standard quietly died from year 1988, the world got to see MSX2, MSX2+ and TurboR extensions of it.
