It seems like the dual/triple boot option using noobs isn't working properly for me (SD-Card issue???)

I wiped my OSMC kodi install from my SD card and installed Retropie 3.3.
From there I use the kodi "app" to get to Kodi. Once there, the wifi android remotes work as they did before.

I have managed to set up the ps3 controller(s) to pair over blue-tooth successfully. This process is actually pretty straight-forward in RetroPie.

This saves me the hassle of switching OS's every time.

Now all I need to do is check is if my ps3 controllers can be configured to control Kodi.
