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.

I guys are following the discussion :)
Whit my bad english it's already difficult to made an example........

Damn... when i made the video whit GB and CATRAP for the other my thread I could show you the example of this too :)

I also had to post the gamelist.xml but it just passed my mind ... really sorry ...

Sure, no need for a hurry.

To clarify on backends.cfg: If it shows jzintv="dispmanx" the emulator call gets these environment variables passed in: SDL1_VIDEODRIVER=dispmanx SDL_DISPMANX_WIDTH=1600 SDL_DISPMANX_HEIGHT=1200 /opt/retropie/emulators/jzintv/bin/jzintv ... (but has no effect on the emulator), if it is absent or configured to SDL2 KMS in _Configurations/Tools _ (results in jzintv="default" in backends.cfg) no env variables are prefixed to the emulator call. So long story short: No need to explicitly set something in backends.cfg.

On readline: You are right, if it is disabled in the build, a simplified implementation will be used. So I will leave libreadline-dev in the dependencies.

Will file the two PRs shortly, will use $__archive_url.

Thanks again.

@duckmefast That only rotates the display 180 deg. - 90 or 270 deg. rotations are still not supported by the Pi4 via config.txt.

@cyperghost got it. I am attempting to change my setup from a nespi case to an onoffshim with a non momentary switch. I used your instructions, to setup the onoffshim, but the system cuts power as soon as i press the button to initiate the shutdown script. (No 3 blinks, just off).

Could the original install of the raspi-gpio for the nespi case impacting things?

@mitu
i have created an suggest on libretro github

https://github.com/libretro/RetroArch/issues/12434

I don't know if it's the correct ways but i was already registered on github so why not try :)

If you know someone on libretro/retroarch developers team pass the suggest to him :)

@clyde i have a custom solution for this since im running on ODROID with SDL2 and so if im not quitting the process soon enough im getting graphical glitches with on screen borders or other weird problems:

This is my solution by now - its not perfect since it can make problems when a rom cant load (then i have to restart the system) otherwise it works flawlessly on my ODROID with retropie:

Basically i have 2 scripts
runcommand-onstart.sh (mine did not exist since i installed retropie from the distro directly)

pkill fbi pkill tail # the image i want to load loader="/etc/emulationstation/splashes/$1/launching.png" if [-f "$loader"]; then # if image is found - start fbi with the image and no timelimit, also start the check script in same directory fbi -1 -t 0 -noverbose -a "$loader" </dev/tty &>/dev/null & (/opt/retropie/configs/all/check.sh) & fi

and the check.sh script:

# you have to enable retroarch logs - always log everything input=/opt/retropie/configs/all/retroarch/logs/retroarch.log timeout 15 tail -f $input | while read LOGLINE # if any of this lines are seen - kill everything related to launchimages - in this case fbi and tail # "Found display server" is the first command in the log before the emulator kicks in do if [[ $LOGLINE == *"Found display server"* ]]; then pkill tail pkill fbi fi if [[ $LOGLINE == *"Failed to load content"* ]]; then pkill tail pkill fbi fi if [[ $LOGLINE == *"Bus error"* ]]; then pkill tail pkill fbi fi done

So what this is doing:
it starts FBI forever and the check script checks the logs for "exit tokens" - if a exit token is hit every process related to the imageloading gets killed.

If the rom cant load before 15 seconds (timeout 15 - set this to the possible highest value) the process should get automatically killed.

works btw with the newest (current master in repo) mame-plus and mame emulators at my side. If you have "Enter Problems" - do what i said before - just add the clean commands for the tty additional to the pkill commands

maybe that idea/solution gives some ideas to you :)

Hey @A12C4 yes to behave like the carousel in wheel mode, a bit like the game wheel in hyperspin I guess. A vertical single grid that is rotated slightly.

I understand no problem, just thought I'd bring this up for a future update :)

There are a few things that I would love to see before this anyhow, such as sound scroll for the gridview, that would be awesome!

@reverieware give it a shot. it cant hurt.

as for adding things to the Retropie setup. as far as i have read from the devs. just submit the script through the github and they review it. but i think they are more worried about getting things running smooth then adding more ports. at the moment at least

that why i just hold on to anything i make. maybe one day ill send them in

@hex I know this thread is a bit old but I want to see if there is interest.

I've added three new events to support integration with the Pixelcade LCD Marquee:

game-select
system-select
screensaver-select

How would I go about incorporating these into the main branch?

FWIW it is currently only in the development branch of emulationstation.

Leave Emulationstation.
ssh with account pi to your pie:

sudo su cd Retropie-Setup

Then you will have to do the "three chord":

./retropie_packages.sh emulationstation-dev sources #1 ./retropie_packages.sh emulationstation-dev build #2 ./retropie_packages.sh emulationstation-dev install #3

If you want to adjust the delay do use this line before proceeding to step 2 and 3.

HTH

even a pop up or on screen option by pressing a button
