I have an old AppleTV lying around and I experimented with and installed OpenELEC witch worked quite nice. But I don’t really have a need for another mediacenter. During the old ATV days I used a ROM emulation plugin. It actually just started some emulators and loaded the selected roms. It worked quite well but I want something more smooth. I found Lakka and it seems perfect as it is based on OpenELEC. I tried to boot it the way the OpenELEC appletv distro boots but I failed. I’ve documented some of my steps here:https://github.com/libretro/Lakka/issues/144
I’m willing to spend more time on this if there are other people interested in this stuff. But I would need some help from you guys, as I’m not very familiar with linux distro building and stuff like this. I think the solution to this is to have an image that looks the same way as the Lakka.TV image (separate KERNEL and SYSTEM images) and compile the kernel with some settings from OpenELEC. Basically and OpenELEC ATV build works with the Lakka SYSTEM image, just KMS is not enabled in the openelec kernel. Maybe that would be sufficient.
