MSX2+¶
Overview¶
MSX2+ arrived in 1988 as an incremental MSX2 revision with richer video features and sprite handling. REG-Linux labels it msx2+ for metadata grouping.
Quick reference¶
- ROM folder:
/userdata/roms/msx2+ - Accepted ROM formats:
.dsk,.mx2,.rom,.zip,.7z,.cas,.m3u - Emulators: RetroArch (
libretro: bluemsx,libretro: fmsx), openMSX, CLK - System group:
msx
| Emulator/Core | Notes |
|---|---|
libretro: bluemsx |
Same options as MSX2 with extra focus on MSX2+ sprites |
libretro: fmsx |
Smaller core tuned for handheld-style performance |
openmsx |
openMSX implements the MSX2+ BIOS list described in msx2.md |
CLK |
Clock Signal reuses the MSX2+ ROMs introduced earlier |
Technical specifications¶
- CPU: Zilog Z80-compatible core (around 3.58 MHz) with the V9958 video chip managing advanced graphics.
- Memory: 64–512 KB RAM with expanded video RAM and mapper banks, allowing more sprites and tile data.
- Display: Yamaha V9958 offering 1920×212 interlaced modes, 192 colors on-screen, hardware palettes, and sprite scaling.
- Sound: AY-3-8910 PSG plus PCM and DAC capabilities from the V9958 for richer audio.
Supported ROM extensions¶
dsk, mx2, rom, zip, 7z, cas, m3u, ogv, openmsx
ROMs¶
Store MSX2+ titles in /userdata/roms/msx2+ and wrap multi-disk games in .m3u playlists for tidy gamelist entries.
BIOS¶
Use the same BlueMSX/FMSX BIOS collection described in msx2.md; the MSX2+ relies on MSX2.ROM, MSX2EXT.ROM
and the additional mapper files listed earlier.
Emulators¶
RetroArch¶
RetroArch hosts libretro: bluemsx and libretro: fmsx for MSX2+ games. They expose the same msx2.* / msxturbor.*
options as the lower-tier MSX systems.
libretro: bluemsx¶
Same configuration as MSX2; include global.bluemsx_nospritelimits and the rewinding/autosave options (msx2.rewind,
msx2.autosave, msx2.padtokeyboard, msx2.cheevos).
libretro: fmsx¶
Mirrors the MSX2 settings and adds msx2.netplay.
openMSX¶
openMSX reuses the msx2.* option group and the BIOS list from msx2.md.
CLK¶
CLK began supporting the MSX2+ standard at REG-Linux 42, sharing the same BIOS files and msx option tree with other cores.
Controls¶
MSX2+ uses the same REG-Linux RetroPad overlay as MSX1/2.
