MsxDS is an emulator of MSX/MSX2/MSX2+ computers for Nintendo DS/DS Lite. Requires a flash card adapter with DLDI support to work.

MsxDS is based on fmsxDS v.0.07 from Nyagosu but since then, several bugfixes and improvements have been added. Moreover, emulation has become much faster.

Installation

  1. Unzip the archive and copy the fmsxDS.nds file on your flash card.
  2. Copy the /msxds folder that contains Carts.crc, CMOS.ROM, data.001, data.002, data.003 and data.004 files at the root of your flash card.
  3. Copy MSX/MSX2/MSX2+ japanese BIOS, FM-PAC BIOS and Kanji ROM into this

folder. Here's the list of the different files:

  • MSX.ROM = BIOS MSX1 & BASIC from National CF-2000 or FS-4000 (CRC32: EE229390 or 071135E0)
  • MSX2.ROM = BIOS MSX2 & BASIC from National FS-4700 or FS-5000 (CRC32: 9B3E7B97 or A44EA707)
  • MSX2EXT.ROM = MSX2 Extended ROM from National FS-4700 or FS-5000 (CRC32: 4A48779C or 43E7A7FC)
  • DISK.ROM = Disk Basic & BDOS ROM from Panasonic FS-FD1 FDD extension (CRC32: 697EAF4E or 4C9B8214)
  • FMPAC.ROM = FM-PAC BIOS ROM from Panasonic SW-M004 cartridge (CRC32: 0E84505D)
  • KANJI.ROM = JIS 1st+2nd Class kanjis ROM from Panasonic FS-A1WSX (CRC32: 1F6406FB) (256KB)
  • MSX2P.ROM = MSX2+ BIOS & BASIC ROM from Panasonic FS-A1WSX (CRC32: 19771608)
  • MSX2PEXT.ROM = MSX2+ Extended ROM from Panasonic FS-A1WSX (CRC32: B8BA44D3)
  • A1WXKDR.ROM = Kanji Basic ROM from Panasonic FS-A1WSX or FS-A1WX (CRC32: B4FC574D or A068CBA9)
  • CMOS.ROM = To save parameters of SRAM used into MSX 2/2+.

Check out the checksums for optimum functioning. DLDI patch is required.

Note: For the Supercard SD/miniSD, please use the following DLDI driver.

Unzip the archive and copy the dldi.scp file into micro SD root directory. The DLDI patch will be applied automatically at launch. NeoDS works fine too with this driver.

Control

A- OK / Button 1 of MSX joypad / Left mouse button

B - Back to previous folder / Button 2 of MSX joypad / Right mouse button

Y - Cartridge, Floppy or Tape ejection

Start - Main menu Display

Pad - Pad of MSX Joypad 1 (Cursor keys or Joypad 2 possible)

In some cases, certain buttons may change function depending from the started game. With 'Fire Ball' or 'Roller Ball' in ROM version, L and R triggers are used to control the flippers. With 'Metal Gear' 1 or 2 in ROM version, L and R triggers are used to press F2 and F3 keys faster, etc.

Known issues

  • The video memory of V99x8 is still managed as fMSX. Ie in one block of 128KB instead of 2 x 64K. This causes graphics bugs in some games.
  • The keyboard support a japanese Bios only.
  • The keyboard is malfunctioning with a few softwares.

Tip & Tricks

  1. Run a european game on tape at 50Hz.

Enter first the following instruction in MSX2 mode before launch the game. VDP(10) = VDP(10) OR 2

  1. Run a soft that crashes on launch.

Edit the BASIC launcher of corresponding soft, seek instruction POKE-1,0 or POKE-1,255 then replace it by POKE-1,(NOT(PEEK(-1))AND240)*1.0625
