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.
