I've been creating Lakka and RetroPie style builds of OpenELEC/LibreELEC for the past few years. Recently, I purchased an ODROID-XU4 for my new bartop arcade system. This appliance style "JeOS" Linux distribution is perfect for running emulators, as it boots lightning fast and uses a minimum of resources.
This image boots up directly into Emulationstation or Kodi/RetroArch. The emulators are integrated; simply put ROMs in the /storage/roms directory via SMB. Emulators commonly auto-detect controllers, however, Emulationstation must be configured manually, except DS4 which is pre-configured. A keyboard might come in handy for initial setup.
- Based on LibreELEC
- Compiled from source with the following CFLAGS: -O2 -march=armv7ve -mtune=cortex-a15.cortex-a7 mcpu=cortex-a15.cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4 -flto
- Built for GBM KMS/DRM (no Xserver and no fbdev)
- Latest Linux 5.0.3 kernel from @memeka
- F2FS/BTRFS/XFS support
- ODROID WiFi/Bluetooth modules work “out of the box”
- Emulationstation (RetroPie fork) is the default frontend that launches the emulators; the default can be changed in /storage/.config/frontend.conf and RetroArch can also be launched through its menus
- RetroArch (git master) with recording capabilities
- Libretro cores: desmume, dosbox-svn, fbalpha, mame2003-plus, mame2016, mgba, mupen64plus, pcsx_rearmed, ppsspp, puae, quicknes, reicast, scummvm, snes9x, snes9x2010, vice_x64, yabasanshiro
- Standalone emulators: PPSSPP, Dosbox-SDL2, amiberry
- Pulseaudio/BlueZ set up to accept A2DP (bluetooth audio) so you can stream music from your phone or laptop while gaming, simultaneously
- big.LITTLE cgroups (emulators are run exclusively on the big cores)
- htop enhanced with big.LITTLE support
- USB IRQs assigned to big cores
- Utilities: scraper tcpdump rsync unrar p7zip cgroup-tools sdl-jstest mediainfo strace screen omxplayer
- Services: Docker, Transmission, SABnzbd, Plex (automatically downloads/updates and installs through the systemd unit), ttyd (shell access from a browser)
You can start the services that you want via SSH with the following command structure:
$ sudo systemctl enable/start [docker | transmission | sabnzbd | plex | ttyd]You can download RetroELEC from https://tinyurl.com/yynfv8m5. If you want Kodi to be included, you can find those images in a separate subfolder. The source code is available on Github at https://github.com/escalade/RetroELEC.tv.
