msxDS is a MSX/MSX 2/MSX2+ home computer standard emulator for the Nintendo DS/DS Lite/DSi console.

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

Unzip the archive, DLDI patch fmsxDS.nds and copy it on your flash card.

Copy the /msxds/ folder that contains CMOS.ROM, Carts.crc, data.001, data.002, data.003 and data.004 files into root of your flash card.

Copy MSX/MSX2/MSX2+ japanese BIOS, FM-PAC BIOS and Kanji ROM into this folder. Below are the list of files that you need to prepare:

MSX.ROM - MSX BIOS and BASIC
MSX2.ROM - MSX2 BIOS and BASIC
MSX2EXT.ROM - MSX2 ExtROM
MSX2P.ROM - MSX2+ BIOS and BASIC
MSX2PEXT.ROM - MSX2+ ExtROM
DISK.ROM - DiskROM and BDOS
FMPAC.ROM - FMPAC BIOS
KANJI.ROM - KANJI ROM (JIS 1st+2nd Class)
A1WXKDR.ROM - Kanji Basic from FS-A1WSX
CMOS.ROM - To save parameters of the MSX.

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.

User guide

Controls

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 are used to control the flippers.
• With Metal Gear 1 or 2 in ROM version, L and R are used to press F2 and F3 keys faster, etc.

Tip and Tricks

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

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

Controls

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

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

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.
