Introduction

NLMSX is an msx/msx2/msx2+ emulator that is based upon fMSX 2.0b made by
Marat Fayzullin and is being developed by Frits Hilderink, a former member
of MSX Computer Club Enschede in the Netherlands.

At this moment the VDP emulation has been completely replaced.
Other parts to be replaced:
 
disk used, but adapted to make diskchanges possible
megarom only konami's that use bank switching at the addresses:
5000,7000,9000,b000
memory mapper used, but will be replaced to enable multiple memory mappers
SCC currently not used
PSG currently not used
FM-PAC currently not used
Mouse currently not used

 

Files


A short explanation of the directory structure:
 
 
Directory File Description
.
MSX2.EXE Main Program.
.\dsks Directory which contains disk images.
drivea.dsk Disk image to be used as 'drive A'.
This file can be renamed/change on the fly. The disk will be just be
offline inside the emulator if the file is not present.
Be sure that this file is not read-only, this bug will be solved.
.\log Directory which contains several log files.
VDPDebug.txt Video Display Processor debug messages.
.\roms Directory which contains the rom images.
carta.rom Rom image for cartridge slot 1.
cartb.rom Rom image for cartridge slot 2.

msx.rom
msx2.rom
msx2ext.rom
