Thanks for reply.
So I am using raspberryPi 3+
My recalbox version is : 7.1.1-Reloaded.
I downloaded it from recalbox page, if I remember correctly, and I have flashed my sd card.
When I check Bios Checking Function for PSX it says that all is OKAY - green status.
I will verify and take your sugestions into consideration.
Will ping you with status
