Philips P2000

[datakneus]

Any chance in adding the Philips P2000 emulator by Marcel de Kogel to RetroPie?

I believe the source code is available : here

Although this post is quite old it seems still relevant and it shoud be nice if it could be added to RetroPie.

I did some investigation about the Philips P2000.

The fastest way of emulating the P2000 is to use DOSbox and the P2000 emulator for DOS.
This is my directory structure :
/home/pi/RetroPie/roms/EmuOnDos/Philips_P2000T/M2000.exe (emulator)
/home/pi/RetroPie/roms/EmuOnDos/Philips_P2000T/games (.cas files)
/home/pi/RetroPie/roms/pc/EmuOnDos/P2000T (all executable .sh starters for .cas files)
An .sh starter contains the following, were as "leeg.cas" can be any .cas file :
/home/pi/RetroPie/roms/pc/EmuOnDos/P2000T/leeg.cas.sh :

#!/bin/bash
/opt/retropie/emulators/dosbox/bin/dosbox -fullscreen -scaler normal3x -c "@echo off" -c "mount c: ~/RetroPie/roms/EmuOnDos/Philips_P2000T" -c "cls" -c "c:" -c "m2000 -verbose 0 -boot 1 -tape games/leeg.cas" -c "exit"

I also tested the source code on raspbian stretch.
The source code is 22 years old but it still works.
I've got the UNIX/X version working again by adding bpp!=24 in X.c.
Compiled with :

make -f Makefile.X

Installed alsa-oss for OSS emulation though alsa

sudo apt-get install alsa-oss

A proper command, that works from every directory, can be (aoss is for sound):

aoss /your/emulator/dir/m2000 -video 1 -boot 1 -tape /your/emulator/leeg.cas -font /your/emulator/dir/Default.fnt

Beware, the emulator stops if the window is not active, so click on the emulator window.

By the way : "I'm not that good in C programming, still learning".
But it seems that for running this code in RetroPie there are a lot of to do's.

To Do's :

• make one universal version that can be run in X and also in RetroPie;
• if in a window, add more windows scalablility;
• add SDL video and audio;
• if SDL audio is a problem then add Alsa audio;
• remove SVGAlib version.

Who has a good idea of making the source code work in RetroPie ???

This is an update on running Philips P2000 emulator of Marcel de Kogel "M2000.exe" on lr-dosbox.

Philips-P2000 on RPI4 32 bit OS (Buster) with lr-dosbox :

Change a few core-options in /opt/retropie/configs/all/retroarch-core-options.cfg :

dosbox_cpu_cycles = "9"
dosbox_pcspeaker = "true"

Make a bat file for example Lazy-Bug.bat :

@echo off
cls
c:
m2000 -verbose 0 -boot 1 -tape games/Lazy-Bug.cas
exit

Place it in :
/home/pi/Desktop/roms/pc/P2000/Lazy-Bug.bat

Games should be in :
/home/pi/Desktop/roms/pc/P2000/games/Lazy-Bug.cas

Emulator should be in :
/home/pi/Desktop/roms/pc/P2000/M2000.EXE
With these other files :
BASIC.BIN CWSDPR0.EXE M2000.TXT
CWSDPMI.DOC CWSPARAM.DOC P2000ROM.BIN
CWSDPMI.EXE CWSPARAM.EXE
CWSDPMI.ZIP DEFAULT.FNT

Automatically make all .bat files from .cas files in /home/pi/Desktop/roms/pc/P2000/games/*.cas :
open terminal and paste these commands :

cd /home/pi/Desktop/roms/pc/P2000/
for file in $(ls games | cut -d '.' -f 1); do touch $file.bat; echo -ne @echo off '\n'cls'\n'c:'\n'm2000 -verbose 0 -boot 1 -tape games/$file.cas'\n'exit > $file.bat; done

Works pretty good :)

I read somewhere that cassette support was added in lr-mess for the P2000T.
(EDIT : found proof of it (Erwin Jansen is busy with it): https://github.com/libretro/mame/blob/master/src/mame/machine/p2000t_mdcr.h )

Nowadays there are many systems added through valerino's setup scripts.
So I made a "valerino alike" script for installing p2000t for lr-mess to see if it could work with -cass files.

Copied the bios files in the root of the BIOS directory.
p2000t.zip
saa5050.zip

Extracted the command from the log for running manually, for testing :

With cass file ( initializing error / no boot, log Error: unknown option: -cass) :

/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/p2000t/retroarch.cfg p2000t /home/pi/RetroPie/BIOS -cass "/home/pi/RetroPie/roms/p2000t/Lazy-Bug.cas" --appendconfig /dev/shm/retroarch.cfg

Without cass file (it boots in colour) :

/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/p2000t/retroarch.cfg p2000t /home/pi/RetroPie/BIOS --appendconfig /dev/shm/retroarch.cfg

Conclusion (binary version of lr-mess) :
With the latest binary from Retropie no cass support yet.

Conclusion (source version of lr-mess) :
?not tested yet?

Today I installed the lr-mess source code version to test if cassette support has been added for P2000T.

I CAN CONFIRM THAT CASSETTE SUPPORT HAS BEEN ADDED AND WORKING.

Thank you Erwin Jansen.
Nice job !!!

Automatically booting, see the upper-left corner.

@theburgerking

I read your thread on P2000T.

Perhaps you find this interesting.

It is still an early discovery, so not all information/scripts are available yet.

But it seems to work pretty good !

Early steps to install :

• use @valerino's fork of RetroPie-Setup (https://github.com/valerino/RetroPie-Setup)
• install lr-mess from source (can take up to 6 hours on pi4)
• add the P2000T valerino alike script from (00-scriptmodules-00/libretrocores) : https://github.com/FollyMaddy/RetroPie-Share
• copy this to : /home/pi/RetroPie-Setup/scriptmodules/libretrocores
• install lr-mess-p2000t.sh in RetroPie-Setup
• add p2000t.zip & saa5050.zip to /home/pi/RetroPie/BIOS
• place the cas files in : /home/pi/RetroPie/roms/p2000t

This is an update on running P2000T on an original RetroPie version.

• install lr-mess from source (can take up to 6 hours on pi4)
• install run_mess.sh from the valerino fork

wget -nv -O /home/pi/RetroPie-Setup/scriptmodules/run_mess.sh https://raw.githubusercontent.com/valerino/RetroPie-Setup/master/scriptmodules/run_mess.sh

• install lr-mess-p2000t.sh in RetroPie-Setup

wget -nv -O /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-mess-p2000t.sh https://raw.githubusercontent.com/FollyMaddy/RetroPie-Share/main/00-scriptmodules-00/libretrocores/lr-mess-p2000t.sh

• add p2000t.zip & saa5050.zip to /home/pi/RetroPie/BIOS
• place the cas files in : /home/pi/RetroPie/roms/p2000t

This is an update on running P2000T using the m2000 emulator by Marcel de Kogel.
(as described in the first post)

I made a module-script for it :

Place it in your RetroPie-Setup folder with :

wget -nv -O /home/pi/RetroPie-Setup/scriptmodules/emulators/p2000t.sh https://raw.githubusercontent.com/FollyMaddy/RetroPie-Share/main/00-scriptmodules-00/emulators/p2000t.sh

Then :

• Install the module-script inside your RetroPie-Setup
• Place the cas files in : /home/pi/RetroPie/roms/p2000t
• When booting a .cas, select m2000 as the emulator

---

Here is some explanation on what the module-script does to get this emulator working properly :

• It installs xorg, matchbox-window-manager and alsa-oss in needed
• It gets the emulator source code of m2000 by Marcel de Kogel
• It patches the X.c file :
  • adding 24 Bits Per Pixel
  • changing video mode 1 to 640x480
  • It makes a boot-script so m2000 runs in lightweight X enviroment (matchbox-window-manager) and uses oss audio simulation (aoss) to get proper sound
  • It adds the default video mode of 640x480@75hz to /opt/retropie/configs/all/videomodes.cfg"
    If it doesn't work for you, then select a better 640x480 video-mode or framebuffer-mode in the boot-menu
• It installs everything

Hopefully more people will enjoy this.
