So, I have a Raspberry Pi 3+ and used to play normally until Dec 2018. A few weeks ago I noticed the Recalbox 6 release and flashed it as usually. But now most SNES games are buggy: some have pixelized boxes instead of normal sprites and others gets black screen. Only a couple of games are running without any error.
How could I troubleshot this? Is there any log that I could search for?
I'm asking this because I don't know if this was a software issue caused after updating or it is a hardware issue (my son let the RPi fall on the floor recently and I didn't like the sound it did).
P.s.: I already tried to redownload Recalbox and reflashed.
P.s.2: Sega MegaDrive Sonic 2 and 3 works perfectly.
