Getting retro-gaming emulation to work with an existing desktop environment OS image is not a good idea. You'd have to enable drm and mali, which breaks a bunch of other stuff making the desktop experience poor.
So here is my suggestion; since you can boot from SD card on the Pinebook, create a dedicated image for retro-games on a SD card which you will be able to pop in and use when you want to play some super mario together.
Use one of the Ubuntu Xenial Minimal images available from ayufan's git.
Here is the script you'll need to run on the on the Pinebook - it installs everything for you; Retroarch (the emulation front-end) and emulators for most 80's and 90's systems :
If you want to make it a learning experience with you daughter then take a look at the script and perhaps just install everything (and set all the values) by hand?
Few things: 1) the minimal image does not automatically connect to WiFi, so you will have to connect from CLI - an additional learning exercise; 2) once you've got Retroarch set up and running, stop the Pinebook from suspending (it breaks Retroarch): instructions here; 3) lastly, here is the original Retroarch thread
