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. | ||
| disk.rom | Rom image for disk support. | ||
| msx.rom | |||
| msx2.rom | |||
| msx2ext.rom |
