Have you tried putting the BIOS files into the same folder where the ROMs are?

Also, try launching the ROMs using a .cue file instead of going directly to the binary. PSX games are kind of a pain this way. Many require .cue files, which are basically just header files which list the disc contents. This Github project has a collection of .cue files:

GameBro Advance is right. Some emulators want their BIOS file in the BIOS directory and some want it in the same directory as the ROMs. I assume his suggestion will fix your problem.
