fMSX3DS is a port of fMSX for Nintendo 3DS. fMSX is an emulator for MSX/MSX2/MSX2+ by Marat Fayzullin. It runs MSX/MSX2/MSX2+ software with very fast on many different platforms including Windows, MacOS, Unix, MSDOS, AmigaOS, etc.

fMSX3DS is compatible with various models (New 3DS, New 2DS, Old 3DS, Old 2DS). Additionally, it incorporates audio emulation by Mitsutaka Okazaki, including emu2413.c. This version is not a legacy release from over 20 years ago; instead, it is the latest version as of 2022.

The emulator also introduces MSXturboR emulation and includes various improvements based on recent analyses of MSX hardware including analyses from Japan that were previously unknown in world wide.

Installation

How to install

Available in CIA and 3DSX formats:

  • CIA version - Install fMSX3DS.cia with your favorite CIA installer (i.e. FBI).
  • Homebrew Launcher - Copy fMSX3DS.3dsx to sdmc:/3ds/fMSX3DS/.

Both versions require dsp.firm in the sdmc:/3ds/ folder on your SD card to enable sound. You can install that with Luma3DS:

  • Open Rosalina Menu with L+D-Pad Down+Select.
  • Select Miscellaneous > Dump DSP Firmware.

BIOS Setup

If you're already using BIOS files for MSXDS, the fMSX core in Retroarch, or the BlueMSX core in Retroarch, fMSX3DS can directly use these BIOS files, so there's no need to set up BIOS separately.

If not, copy following MSX BIOS files to the root of your SD card or FMSX3DS folder:

  • MSX.ROM
  • MSX2.ROM
  • MSX2EXT.ROM
  • MSX2P.ROM
  • MSX2PEXT.ROM

Additionally it is recommended you to use these files:

  • DISK.ROM - To play games with disk image.
  • KANJI.ROM - Display Japanese KANJI.
  • FMPAC.ROM - To enable FM Music and SRAM save.
  • A1WXKDR.ROM - KANJI BASIC. Some MSX2+ games need this. Also needed for Show up MSX2+ bootup screen.

As to "A1WXKDR.ROM", you can replace that with the "MSXKANJI.ROM" or "KNJDRV.ROM".

If you want to play the MSXTurboR you need these files:

  • MSXTR.ROM
  • MSXTREXT.ROM
  • MSXTROPT.ROM
  • MSXKANJI.ROM (A1WXKDR.ROM, KNJDRV.ROM)
  • MSXDOS23.ROM
  • MSXTRMUS.ROM

Notes:

Paths

fMSX3DS creates these folders:

  • /FMSX3DS/SAVEDISK - Saved Disk.
  • /FMSX3DS/SNAP - Screen Shot Image.
  • /FMSX3DS/SRAM - S-RAM Save Data.
  • /FMSX3DS/STATE - Saved State
  • /FMSX3DS/TAPE - Saved Cassette Tape

User guide

ROM selection

When you start fMSX3DS, it show select file dialog.

You can select ROM cartridge, Disk image, Cassette Tape etc.

fMSX3DS supports files with extension ".ROM", ".MX1", ".MX2", ".DSK", ".CAS".

Also, It supports ".ZIP" or ".gz" compressed files.

Special Hardware

+PCM

+PCM is ADPCM Voice Sampling hardware used in some Japanese homebrew/doujin games, notably Pleasure Hearts.

To enable it in fMSX3DS, select the "[Option]" item in the system menu and change the "<Input/Output Hardware Option>/Printer Port" to "PCM+".

VoiceBox

VoiceBox is another type of PCM Voice Sampling hardware. Only one commercial game, Isseki ni Kakeru Seishun by LOG, supports this hardware.

To use VoiceBox in fMSX3DS, select the "[Option]" item in the system menu and change the "<Input/Output Hardware Option>/Printer Port" to "Voice Box".

Stereoscopic 3D Glasses

Some MSX games and test programs support stereoscopic 3D, like Dim X by Kai Magazine.

To enable stereoscopic 3D on Nintendo 3DS with fMSX3DS, move the 3D depth slider up, then select the "[Option]" item in the fMSX3DS system menu.

Change the "<Graphic Setting/Use 3D Stereoscopic>" option to choose from available modes, currently including anaglyph 3D and anaglyph 3D (Color).

V9990

Some homebrew game/app requires V9990 or ites clones(GFX9000 etc).

To use that, Chose "[Option]" item in the fMSX3DS system menu, and enable the "Use V9990" option item.

MSX0

MSX0 is an official MSX project started in 2023. The device enables connection to various IoT devices for control via MSX. Many people create homebrew or doujin games/apps with this feature. To use MSX0 with fMSX3DS, select the "[Option]" item in the fMSX3DS system menu and enable the "Use MSX0" option.

fMSX3DS uses a fake MSXIOT ROM file for MSX0, so no MSXIOT ROM file is required. However, some MSX0 games/apps need the MSX-BASIC KUN (X-BASIC) ROM.

If you are not using BlueMSX core for Retroarch, you have to rename MSX-BASIC KUN PLUS (X-BASIC2) ROM to "MSX0_XBASIC.ROM" or "XBASIC2.rom" and copy it to the ROOT of your SD card or "FMSX3DS" folder ("root\FMSX3DS"). Then, select the "[Option]" item in the fMSX3DS system menu and enable the "<MSX0 Option>/Load X-BASIC2" option.

For the touch screen of MSX0, you can use it by tapping the mouse icon on the lower right of the bottom screen when the "Use MSX0" option is enabled.
