MSX emulator for MSX! Version 1.0

This is a teaser... expected release date tomorrow, when I've done some more testing...

MSX emulator for MSX tR	version: 1.0
------------------------------------
Made By: NYYRIKKI 2009

This program will try to emulate original 64K MSX1 computer accurately.
This includes motor relay sounds, diskdrives that keep spinning etc.
To use this program you need MSX tR and dump of MSX1 ROM.

This file needs to be named "MSX.ROM" and emulator needs to be started
from same directory where the file is located. To enjoy all the features
Harddisk / CD / CF tms. is also recommended.

Emulator is started simply by typing "MSX1EMU". There are no commandline
parameters, so you need to use commands from emulated computer.


List of supported commands:

	_CHDIR ("[<drive>:]<path>")
		Set default drive & path on host OS.

	_FILES [("[<drive>:][<path>][<filename>]")]
		List files from host OS.

	_CHDSK [("[<drive>:][<path>]<filename.DSK>")]
		Select disk image for use. If parameter is not 
		given or it is empty real disk drive will be used.

	_CHCAS ("[<drive>:][<path>]<filename.CAS>")
		Select Casette image for use


	_CASREV
		Revind casette back to beginning

	_CASAUTOREV [ON|OFF]
		Select if cassette should be revinded automatically.
		At least Gauntlet(*) requires this... maybe also some other?

	_IOSOUND [ON|OFF]
		Enable / Disable emulated cassette & disk sounds.

	_EXIT
		Exit back to MSX tR mode.

	_RESET
		Reboot MSX

	_HZ [50|60]
		Select screen refresh rate

	_PALETTE [MSX1|MSX2|GREEN|GRAY]
		Select what palette / monitor emulation should be used.


Examples:

  DISK:

	If you want to start disk game from image, boot the emulator with
	SHIFT-key pressed. This will make sure, that emulator does not start
	from real disk inserted to disk drive.

	To select directory type:
	  _CHDIR("C:\GAMES\DSK")

	To see what DSK files you have, type:
	  _FILES("*.DSK")

	To set correct disk image type:
	  _CHDSK("A:\DSK\MIU2006.DSK")

	To start the disk image type:
	  _RESET

  CASETTE:

	To get maximum free memory it is recommended to start the emulator
	SHIFT-key pressed.

	To set correct CAS-image type:
	 _CHCAS("A:\GAMES\CAS\GAUNTLET.CAS")

	Games can be usually loaded with one of the following commands:

	BLOAD"CAS:",R
	RUN"CAS:
	CLOAD

MSX memory layout:

	0-0	MSX-BIOS (#0000-#7FFF)
	0-1	Not in use
	0-2	Not in use
	0-3	Not in use

	1	Not in use

	2	Not in use

	3-0	64K RAM
	3-1	DISK ROM
	3-2	Host OS commands
	3-3	Not in use


(*) The original version of Gauntlet does not work on computers that have
slot 0 expanded. To fix this, dump both sides of the cassette. Then
put #00 to CAS-file offset #5C20 and #D386 Last copy both sides together
as one file and remember to execute "_CASAUTOREV ON"

Happy gaming!
