@loak so, I did the fresh install and the same errors keeps occuring. What else can I do?

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.

Prezados, estou há exatas 6h tentando instalar o Recalbox 4.4 no meu Raspberry Pi 2.
Sou usuário avançado em Linux, hoje testei o Lakka e o RetroPie, todos flashando via "sudo dd if=[...] of=[...]", mas o Recalbox não boota por nada. Já tentei flashar também usando o Etcher, e nada.

Peguei a versão em .zip e unzipei no SD Card, funcionou legal. Só a versão em .img que não roda.

Não sei mais o que fazer. Aceito sugestões.
