To play some old computer games with RetroPie I installed retrosmc on my Raspberry Pi running OSMC.
I was trying to play the retro game “Wacky Wheels” with DOSBox. Unfortunately my USB Gamepads were not able to handle the configuration of the input. So I wrote a small python script which maps gamepad inputs to keyboard inputs.
The script is shown below. It is executed with the start-script of “Wacky-Wheels” in “/home/osmc/RetroPie/roms/pc”:
python /home/osmc/joystick.py &
/opt/retropie/emulators/dosbox/bin/dosbox -c "mount c /home/osmc/RetroPie/roms/pc" -c "c:" -c "cd WACKY" -c "WW.EXE" -c "exit"
Also it is important to have joysticktype=none in your dosbox-SVN.conf
Since Raspbmc is no longer under development I upgraded to the enhancement called OSMC.
After installing OSMC on my SD card I tried to enable the device tree overlay for the GPIO IR Remote. This can be accomplished in the OSMC Settings Plugin or in the file /boot/config.txt by adding:
Furthermore you need to delete the lircd.conf in /etc/lirc and store your version created for the remote at /home/osmc/lircd.conf. It is important to edit the “name” entry.
To enable the key functionality you need to add a Lircmap.xml to map the keys.
More information can be found in the entry on the OSMC forum: https://discourse.osmc.tv/t/rpi2-osmc-alpha-4-and-ir-gpio/483/12
You will need to configure a Lircmap.xml file and place it in /home/osmc/.kodi/userdata folder.
If there is none avaialable there, take the default one from here
and modify it.
Keep only one entry and make sure that the LIRC button names are correct (keep onet hat has KEY_LEFT, KEY_RIGHT, etc. in it).
Make sure you use the same name for the remote device name with the one configured in /etc/lirc/lircd.conf (if it’s generated, the name is the path where it was created. Feel free to rename it to something more handy, like ‘myremote’)
More info here:
Place the edited Lircmap.xml file in the /home/osmc/.kodi/userdata/Lircmap.xml and then restart kodi (or the RPi).
Ambilight with Hyperion
To enable the ambilight functionality I replaced Boblight with the lightweight Hyperion. The installation and configuration process is described in the wiki: https://github.com/tvdzwan/hyperion/wiki/Installation and https://github.com/tvdzwan/hyperion/wiki/Configuration.
Unfortunately the LEDs weren’t working in my setup. To debug the hyperion process you can start it with
sudo /usr/bin/hyperiond /etc/hyperion.config.json
While debugging I found a XBMC Connection Error (0) which is described in the forum: https://discourse.osmc.tv/t/rpi2-hyperion-osmc/449/43
The solution is to create a init script in /etc/systemd/system/multi-user.target.wants/hyperion.service
Description = hyperion
After = mediacenter.service
User = osmc
Group = osmc
Type = simple
ExecStart= /usr/bin/hyperiond /etc/hyperion.config.json
Restart = always
RestartSec = 1
WantedBy = multi-user.target
