Retropie 4.6 real cd-rom support

sarahsen

Good morning to all,
I’m doing some tests with the support of the real cd-rom and they work very well with the following consoles : pcengine cd, neogeo cd, nec pcfx, sega mega cd but it doesn’t work with the playstation maybe for incompatibility with the core.
I wanted to know if there is a method to launch the cd from emulationstation by creating a script without having to retroarch all the time.

I can confirm that the system works with the following systems : Sega Mega cd - Neogeo CD - Pc engine CD - Nec Pcfx - Panasonic 3d0 all about rapberry pi4 and the new version of retropie with retroarch updated to the latest version.

I am trying to create a script to launch cd-roms directly from emulationstation but without success.
Who has any idea how to create it ?

From what I've seen, you can launch directly RetroArch with the CDROM by specifying cdrom://drive1.cue as the ROM name. There's no support at the moment in RetroPie for this, but maybe it could be added in the future.

This is how you can launch it from the command line

/opt/retropie/emulators/retroarch/bin/retroarch -L <path/to/libretro_core> cdrom://drive1.cue

Actually, this could be done with an entry in the system's emulators.cfg.

Let's say you want to start a SegaCD game from your connected disc drive. Open up \\retropie\configs\all\segacd\emulators.cfg and add a line containing

lr-genesis-plus-gx-cdrom = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/segacd/retroarch.cfg cdrom://drive1.cue"

Then create a Load Disc 1.cue file in the roms/segacd folder and restart EmulationStation.

Start the Load Disc 1 game that should be there, then use the runcommand launch menu to select as emulator the lr-genesis-plus-gx-cdrom emulator.

NOTE: you might need to install lr-genesis-plus-gx emulator first, since I think it's not installed by default. If you want to do this for other systems/emulators, you need to adjust the entries in the emulators.cfg accordingly (i.e. libretro core name and path).

Thank you for your kind answer tomorrow I am home and I can try. As soon as the experiments are done I communicate the result.

Best regards

I have done all the tests with your script and works perfectly Cd-rom start perfectly on the following systems : 3do - Neogeo CD - Pceingine Cd-rom - Sega Mega CD - Nec PC-FX.

I created launchers for all systems and also created a script for ejecting the cd.
everything works perfectly in Emulationstation.

If anyone’s interested, I can post the whole procedure.

Thanks to your advice.
Best Regards

Update : Saturn CD-Roms also work via the core lr-beetle-saturn, runs better with Cd-rom than with Roms, several games are playable we hope they update this core.
All this with a Raspberry pi 4 with 4 gigabyte of ram.
