In theory should be possible with bluemsx (not sure how well implemented the libretro version is) but from what I was reading running .cas looked a bit involved, there was a bit of a guide I saw on the bluemsx forms but I don't think I can link to it as it looked like it had ROM or bios links.

@herb_fargus

Good to know. lr-bluemsx works pretty well in most situations. I forget why I switched over to OpenMSX. It may have had something to do with peripheral support.

@sastremarti

It'll help to draw in opinions and possibilities if you fill out the requested information found at https://retropie.org.uk/forum/topic/3/read-this-first

@weirdocollector said in MSX and .dsk games:

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.

@Jazzy

How many games have you tried and which ones? Some only support the keyboard.

Just found a way to do something, by using Select+X while in the game: from there, a Quick Menu allows me to see the options you mentioned (but not the rom I added, so you may be right about the static options). Anyway, not sure any change I make here is persistent...

@JiggaWatt i dont think the f keys can be mapped to the controller in retroarch. You definitely want to map f1-f4 if you can for metal gear though. Maybe with joymap.

I'm using bluemsx and fmsx.
