For now i can't help you with that.
For myself I tried the Philips-P2000-emulator "m2000.exe" in lr-dosbox.
I have it fully working on normal dosbox :

lr-dosbox is still experimental, so I had also have speed issues, bad audio and keyboard issues.
Perhaps I will try to do some more work in the future.

@Folly

thanks for the share

also thanks for the feedback .. i didn't now ir-dosbox was experimental

Folly

@escc1986

I did succeeded to get it run faster :
dosbox_cpu_cycles = "9"
Perhaps you can improve it too, within the core options.
While running lr-dosbox press F1 and select "options".
(use cursors and x=forward z=back)
Press F1 again to go back. (settings are stored then)
core-options are in :
/opt/retropie/configs/all/retroarch-core-options.cfg
(you can also edit this as a text file)

@Folly

cpu cycles = 9 didnt work well for me ,

it seemed like it slowed things down a bit

.... you are trying cpu cycles 9 on mad dog mcree right ?

plus still no sound , im not sure how to fix the sound

not sure if the instantiation files have to adjust something or if its the ir-dosbox emulation ?

escc1986

@Folly ok right now im at the Sound Settings of the installation screen for " Mad Dog McCree " game

What Settings Do You Prefer ?

Folly

@escc1986
Did not try it on mad dog mcree.
Will have to search for that game.

I used it for my P2000 emulation.

Now works perfect !

You should select the default settings.
You can find them if you turn on advanced core options in retroarch.
dosbox_adv_options = "true"
dosbox_sblaster_base = "220"
dosbox_sblaster_dma = "1"
dosbox_sblaster_hdma = "7"
dosbox_sblaster_irq = "5"
It think it's not necessary to put this in you core options though.

Thanks Folly for your input , I will check those setting out in advanced core options

The Philips P2000 seems very interesting , i have no idea about that Emulator , Could you describe to me in your words what's the Philips P2000 is and how does it work ?

The instructions are a bit confusing to me , but maby you could teach me basic step by step guide what to do first , second , third and so on

I'm so happy that you got it working !!! Pretty amazing ... what kind of games could you play on it ?

What's your favorite game for the Philips P2000 ?

Thanks again for those sound options , I'm going to try it in the morning

@artescc1986 @escc1986
Will try and see if i can make a proper guide for everyone in the future !

The P2000 is an all in one Z80 computer with microcassette and cartridge slot.
It's a sort of pre-MSX1 and uses the basic language.
It contains a teletext processor(developped for TV) for graphics.
So it looks like your watching teletext.
You can connect it to a TV with an antenna cable.
It could also send teletext to the TV if you selected that.
It was mainly sold in the Neterlands. I did have one too.
Nice thing about the microcassette was that it works like a diskdrive.

The best game is Lazy-Bug, it's a pacman like game.

I tried 10 games on lr-dosbox on my RPI4.
(I kept the dosbox_cpu_cycles = "9" line in the core-options)
Got 5 working perfect.
I also found "mad dog mcree" and tried it.
No speed issues and there is also sound.
Though I have no mouse emulation, so i can't play the game !!!
Seems this can be solved if analogue axis of the joystick are configured.
Have to figure that out later.

Make this directory copy the ISO to this directory :
roms/pc/Mad Dog McCree (1993)/cd/
Make a .bat file in roms/pc/Mad Dog McCree (1993)/install.bat

imgmount D cd/maddog.iso -t iso
d:
install

Install the game which makes this directory :
roms/pc/Mad Dog McCree (1993)/maddog/
Made a .bat file in roms/pc/Mad Dog McCree (1993)/maddog.bat

imgmount D cd/maddog.iso -t iso
cd maddog
maddog.bat

Run the .bat file from roms/pc/Mad Dog McCree (1993)/maddog.bat

Still learning (WIP)
