MSX and .dsk games

[weirdocollector]

Hi,

is it true that in order to use .dsk MSX games it is necessary to install OpenMSX?

I've tried both bluemsx and fmsx, but the former, after a first run of some .rom games now gets me back to ES after displaying a black screen, while the latter works with .rom games, but just goes to the BASIC screen when I load a .dsk game.

I've also uninstalled and re-installed bluemsx, but it still goes into a black screen before returning to ES.

Any help on this?

I'm using Retropie 4.1 on a Raspi3B, with roms on an external HDD, and an xbox one controller.

Thanks a lot!

I personally use OpenMSX to run .dsk games, but there is also the option to use the DSK2ROM utility. Once converted, the games should run in the various RetroArch MSX cores, but I have yet to try it myself.

How do you load .dsk to OpenMSX ?

I've tried just selecting a .dsk from ES, and OpenMSX simply goes into black screen returning me to ES.

.rom files work.

Thanks again.

They should just load right up after being launched from Emulation Station. Have you installed the bios files and set the corresponding machine type from the console?

Done both, but I keep geeting the C-BIOS screen.

Is it possibile that I'm using the wrong BIOS files ?

@weirdocollector if i remember correctly in open msx you need to go into the settings thats on the button on the right of your spacebar that shows a piece of paper on it and change the bios to the correct bios.

Unfortunately, my mini USB keyboard does not have that key.

Anyway I've had a look at the OpenMSX documentation, and there is no mention of a command to switch BIOS: in theory, if you put the correct system roms, in the correct directories, the emulator should automatically start with the correct BIOS.

Any other suggestions ?

This is long overdue and you likely figured this out by now, but for posterity, I'll post what I found to be a solution. I just made the switch the Stretch and this one little issue was the only road block I encountered in restoring my backup from Jessie. The Docs state that you only need to set the desired machine type into the terminal overlay and that the corresponding BIOS will be selected. Needless to say, this didn't work for me either.

@edmaul69 mentioned above that the machine should be selection through the emulator's option menu by pressing the 'Menu' key. That is correct, but the problem is that many keyboards don't have a 'Menu' key. To change this key binding, drop to the terminal and type:

cp /opt/retropie/emulators/openmsx/share/scripts/keybindings.tcl /home/pi/.openmsx/share/scripts/keybindings.tcl 

Then type:

nano /home/pi/.openmsx/share/scripts/keybindings.tcl

After the contents of the script are displayed, look for:

} else { ;# any other
	bind_default "keyb MENU"   main_menu_toggle

My keyboard has a 'HOME' key, so I replaced 'MENU' with that. However, you can put any key you want here, but it should be one that doesn't interfere with the MSX keyboard. Using the 'HOME' key, the replaced test should look like:

} else { ;# any other
	bind_default "keyb HOME"   main_menu_toggle

press 'ctrl+O' to save, 'Y' to verify and exit with 'ctrl+X'. Now you can launch a game and bring up the onscreen menu where you should be able to select a machine ('Philips NMS 8250' for a European MSX2 if that's what you're aiming for). Afterward, bring up the menu again and select the option to make the current machine the default. Now, the chosen machine and corresponding BIOS should be applied every time a game is launched.
