The MSX2 is a computer developed by Microsoft. It was released in 1985. Notable titles include Metal Gear.

Despite this being a product of Microsoft, it's likely you've never heard of this computer. It was primarily popular in the Asian, South American and European regions, but virtually unknown in North America.

Manufacturing was split up among a wide range of companies, including Pioneer, Panasonic, Sharp, Sony, Sanyo, Philips and LG Goldstar. Therefore, there were many different alternative names for the system, including:

  • Panasonic FS-A1
  • Panasonic FS-A1mkII
  • Toshiba FS-TM1

This system scrapes metadata for the “msx” group and loads the msx2 set from the currently selected theme, if available.

Grouped with the “msx” group of systems.

  • Accepted ROM formats: .dsk, .mx2, .rom, .zip, .7z, .cas, .m3u
  • Folder: /userdata/roms/msx2
MD5 checksum Share file path Description

Then extract the “Databases” and “Machines” folders and add them to the bios folder.

For fMSX these files are required instead:


Place your MSX2 ROMs in /userdata/roms/msx2.

Some MSX2 games require multiple disks to play. This can be handled by RetroArch using a M3U playlist. For example:

test game disk 1.dsk
test game disk 2.dsk
test game disk 3.dsk

Batocera will automatically hide the extra disk files and only show the M3U playlist as the playable game in EmulationStation.

RetroArch has its own page.
