Here is a Quad-Boot build of RetroPie, Raspbian (with new ‘Pixel’ desktop), RasPlex and KODI:
This is my first quad-boot build, and it was more a proof of concept really, but it all seems to work just fine so please try it out if you are interested and let me know what you think!
Like in the triple-boot build, I have added 3 versions of KODI – OpenELEC, LibreELEC and OSMC, and you can choose which version you want to install alongside Raspbian, RasPlex and RetroPie.
I have added an ‘Always boot to RasPlex’ option, so now you can choose whether to always boot to KODI or RasPlex (or leave as standard of course!). I have also amended the latest version of the standard PlexHT skin to add in a link to KODI, Raspbian and RetroPie and this time I am using add-ons instead of scripts. I have uploaded the add-ons to the below page but please be aware that RasPlex add-ons cannot be installed the same way as KODI – you have to add them directly to the SD card under /.plexht/addons/ and then find a way to access them through the GUI (such as linking them into the skin like I have):
As always this is a NOOBS installer supporting USB install (which I would highly recommend due to the size of the install files).
All the best.
