Hello, glad to help. Faced these issues in my Rpi:
- Model: Raspberry Pi 3B+, heatsink and fan.
- SDcard: tried 2 - Sandisk 32gb ultra and generic Sandisk 64gb (both showed the aforemented problems)
- Sony Bravia TV (Android) 905E model, 720p, hdmi 1.4 cable
- RPi Font is an original RPi font, never had "lightining bolt warnings" before
- Logitech Gamepad generic USB wired controller (1 unit)
- ROMs are located on the network (NAS).
So my previous Recalbox version was 7.XX (the last version before 8.XX). It was working flawlessly, no issues at all. Everything, everything worked fine, no performance issues.
Installed 8.0.2 via PC (using balena etcher) and as soon I pop the sdcard on the RPI3 all the known problems happened:
- Games froze when launching them (black screen, only the bottom bar of the UI appeared with shortcuts)
- Background music stopped or didnt even start at the boot
- Random but very frequent freezes - sometimes games launched and sometimes freeze with the game playing.
So I tried again, this time updating my 7.XX version (which was in another sd card) from the inside of the Recalbox itself. Update process went smooth, but as soon as it booted for the 1st time, same problems ocurred.
This is as detailed as I could. Hope it helps.
