This still has a bunch of issues - if I use multiple cores, settings for the ‘menu toggle gamepad combo’ do not seem to be saved for each, despite setting it up multiple times.

How do you set up global settings that are the same for each core, unless otherwise specified?

ok now i see what the issue is - you need a very flat rom storage folder structure - once i added a directory directly with the roms in, the emulator icon for gba showed up. these means you can’t store roms by genre or similar, as i was doing.

I got retroarch 1.2.2, but the I do not see a list of emulators as outlined in step 5 :
