There is a new build by DamsRoxxx of the P-UAE core for retroarch that seems to work pretty well. I've made a Retroplayer addon of it; if you want to test it (Windows x64 only) you can find it here:

Infos and instructions for Retroarch are here:
https://github.com/DamsRoxxx/libretro-ua.../README.md

In Retroplayer, you have to put the kickstart roms (named according to the instructions) and the WHDLoad.hdf file in
<userdata>\addon_data\game.libretro.uae\resources\system\
where <userdata> is the location of your userdata folder, that depends on if you have a standard or portable installation (see Userdata (wiki)).

Thanks DamsRoxxx for the great work!

Edit: addon updated. Previously the setting ids were wrong.
