I can't run any PSX games on PC (booting USB using latest v5.3 x64 image). Every time I start game, screen goes blank for few seconds then goes back to ES. I've also tried to run latest image on Pi3 and I'm gettimng message no BIOS found but at least emulator starts and runs my games.
I have BIOS file which shows correct MD5 checksum. It which works for me on RetroPie 4.1 and RecalBox (on my Pi3) as well as with other PSX emus run under Windows. Is this something broken
Another issue is when I try to use 2nd USB stick which has all games and BIOS files. Games located on 2nd USB stick show up in ES but none actually runs. I would love this feature to work as I could use same USB stick with roms for PC and Pi.
