Tried Different ROMs still the same problem, also tried another storage device (Thumb Drive), still the same.

Tried NBA 2k1 and it has the same problem.

Maybe the Pi4 needs to be overclocked? idk

@Zing bios seems fine, i will test core as you said. Tnx

Hi guys!
Im using Recalbox 7.1.1, Raspberry pi4 model B 4GB RAM (not overclocked) and i encountered these problems while playing dreamcast games;

Evolution world of sacred devices - freezes in 3rd ruins (the fire ruins) in 8th floor
NBA 2k2 - freezes when you try to shoot/pass the ball near the ring almost everytime
House of the Dead 2 - Freezes in random areas

Anyone knows if the problem is the core or bios? tnx
