excellent job!, everything seems to work fine now. The audio still cuts out on more demanding libretro cores, but it might be related to the board overheating so I will get a better fan/heatsink and run some tests.
Kodi works better, the menu is bit laggy and HEVC/x265 videos are slow, even on lower resolutions, but I’m aware of this being more on the Kodi’s side than Batocera’s. Although, I will run LibreELEC to compare the performance between systems.
