Hello,
I have some issues on Raspberry Pi 4 with Batocera 5.26 (2020/05/27):
Atari 800 (lr-atari800): No sound. Works on RPI3.
C64: lr-vice is missing. Aspect ratio correction setting is not permanent in vice. Support for tape images (.TAP, .T64) not present in es_systems.cfg.
DOSBox: All Commander Keen games crash in lr-dosbox, only DynaBlaster works. Video output of DOSBox-X only in upper half of the screen, divided into two parts. Looks verry strange and is not playable.
Kodi: Tearing, stutter, block artefacts when playing H.264 videos. Gets a bit better when turning on “Adjust display refresh rate to match video” in playback settings. Works smooth on RPI3.
