Thanks @digitalLumberjack, I'll try! Atari 2600 is giving me same error, black screen and then MENU. I think I'm losing something...

Hello, I'm using recalbox version 4.0.0-build-10 and I just start my new raspberry pi 2 with recalbox and test SNES game and it's ok. I have downloaded a PSX bios and put it on the bios folder, the name and the md5 is the same as sad on _readme.txt (scph1001.bin). When I start the game the screen fade por a second and then back to the game list. I have tried with 2 differents roms (.img/.bin). I'm listening the file recalbox.log and show nothing. Can anyone help me? Thnks
