@zing Yes they are. I checked the MD5 checksum to verify that the files match also.

Hello. I have been playing PSX games in previous versions of Recalbox, but after upgrading I'm no longer able to play them. The system recognizes the games, but after starting them it returns to the frontend. I have installed all four bios files (scph1001, 5500, 5501 and 5502). I have tried with .bin & .cue format and .pbp. I would appreciate any help. Thanks in advance.
