Manually adding emulator(s)?


  • I've been using RetroPie on a Rpi 3b+ for a while now and bought an Intel NUC as replacement: more power for N64, Dreamcast etc.
    I really love RetroPie and to be honest I would love to have it running on my NUC as well.
    But I bought the NUC especially for Dreamcast emulation. I tried Redream (latest closed source edition) on Windows and it runs rather well. There is also a Linux variant.
    Is it possible to have this emulator in RetroPie? Can I manually download it, install it and than use it in RetroPie?

    @Panja redream is included under experimental.

  • Thanks for the fast reply.
    Are you serious?! I though the version of Redream was the open source variant from a few years back.

    This is awesome!

    Is the version that is under experimental a recent version?

    Sorry. It's just the open source libretro core. I missed that bit.

  • Ok, no problem.
    Back to my original question than...

    If it has a version that runs on Raspbian for Raspberry PI, then you maybe have a chance of making it run.

  • There is a Linux variant but I think it's x86.
    But I will be running RetroPie on x86 hardware as well.
    So wouldn't that work?

    If so can you point me in the right direction?

    If you install one of the RetroPie's Dreamcast emulators, you'll have an emulators.cfg file in /opt/retropie/configs/dreamcast, which lists the available Dreamcast emulators. For instance, if you installed lr-reicast you'll get the file below:

    lr-reicast = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-reicast/reicast_libretro.so --config /opt/retropie/configs/dreamcast/retroarch.cfg %ROM%"

    You can add a new emulator for the system with a new line that describes how the emulator should run your ROM

    lr-reicast = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-reicast/reicast_libretro.so --config /opt/retropie/configs/dreamcast/retroarch.cfg %ROM%"
# New Dreamcast emulator
my-emulator="/full/path/to/emulator/program %ROM%"

    and you substitute the values for my-emulator and the path to the emulator. %ROM% will be automatically completed by RetroPie with the full path to the ROM file. Of course, the emulator must support loading a ROM directly and starting automatically with that ROM and it might need additional command line paramers to instruct it to load the ROM - you add the parameters to the command line.

    After you add the lines, use the Runcommand lanch menu to choose your emulator entry for the ROM (or the whole system).

  • Wicked!
    Sounds if it should work.
    As far as I'm aware Redream can load roms from the commandline.

  • Finally got around to test it and I can confirm it works!
    Thanks
