OK, I've looked around for an hour - I've enabled the games menu, added Zach M repo, installed IARL and the Libretro compatibility addon yet despite trying to configure IARL for retroplayer use I just cannot get any game/system to run. All report "cannot find an emulator".
Others seem to suggest "Games" should work in the build. Can anyone suggest anything or provide a few steps they used to get working?
I've installed 8.90.5 img to a USB stick for testing so a clean build from the image file on an S905X device.
Feels like I've just missed an entire step and need to install the desired Libretro cores or something.
