About openMSX

openMSX is an emulator for the MSX home computer system. MSX was a standard

for Z80-based home computers, and was a (largely) Japanese attempt to

establish a single standard in home computing similar to VHS in video.

The MSX standard was designed by ASCII Corporation in Japan, in cooperation

with Microsoft Japan. The later of which provided the extended BASIC for

the machine.

In addition to emulating MSX, MSX2, MSX2+, MSX Turbo R and many of it's

peripherals, openMSX also supports emulating the ColecoVision and

Sega SG-1000 game consoles and the SpectraVideo SVI-318 and SVI-328

home computer systems.

Note: by default the openMSX emulator only ships with the C-BIOS open-source

BIOS implementation. This BIOS is restricted to cartridge based MSX games. For

a full MSX or SVI emulation it is necessary to provide your own MSX and/or SVI

BIOS ROMs, which must be placed in the ~/.openMSX/share/systemroms directory.
