fMSX3DS is the Nintendo3DS port of fMSX (MSX/MSX2/MSX2+ emulator), available for New 3DS, New 2DS, Old 3DS, and Old 2DS systems. In addition, it incorporates advanced audio emulation by Mitsutaka Okazaki (emu2413.c, etc.) with the latest version from 2022. Unlike other emulators that rely on outdated versions from over 20 years ago, fMSX3DS offers the most up-to-date experience. Moreover, it includes numerous enhancements informed by recent analysis of MSX hardware, including exclusive insights from Japan that remain unfamiliar to the wider community.

Installation

CIA vertsion: Install "fMSX3DS.cia" with your favorite CIA installer.(i.e. FBI).

Homebrew Launcher: Copy "fMSX3DS.3dsx" to "/3DS" folder on your SD card.

• Both CIA version and Homebre Launcher version need "dsp.firm" file in the "/3DS" folder on your SD card to enable sound.

Usage

BIOS Setup

If you are using MSXDS, fMSX core for retroarch, or BlueMSX core for retroarch, fMSX3DS load these BIOS files directly and no need for setup BIOS files.
If not, Copy following MSX BIOS files to the ROOT of your SD card or "/FMSX3DS" folder.

• MSX.ROM

• FMPAC.ROM :To enable FM Music and SRAM save.
• A1WXKDR.ROM :KANJI BASIC. Some MSX2+ games need this.
  • Also, Need for Show up MSX2+ bootup screen.

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

• If you miss BIOS, fMSX3DS use the C-BIOS http://cbios.sourceforge.net/.
• C-BIOS is the open source MSX BIOS by BouKiCHi, and many developers modified that.
• You can play almost ROM games with C-BIOS, but it doesn't support Disk games, nor support Programming with MSX BASIC.
• If you miss KANJI.ROM, fMSX3DS use pseudo KANJI.ROM from A to C.
