Hi, and welcome to the forums!  
Let’s grab more details. Exactly which version of the OS are you using? It changed between OS 0.4 and 0.5 for the standalone emulator.  
You mention Retroarch directories, however the PCSX that comes with the gameshell is a standalone emulator and doesn’t use Retroarch.

Here’s the location(s) for the standalone bios to be installed:

> [@Custom D.E.O.T. V2.0+/Clockwork OS v0.5 image - With customised DEOT interface, Kernel 5.7, Optional 1400MHz OC, Debian 10 Buster, Retroarch 1.9.0, Mupen64+ plus more! (Current build: 200903)](https://forum.clockworkpi.com/t/custom-d-e-o-t-v2-0-clockwork-os-v0-5-image-with-customised-deot-interface-kernel-5-7-optional-1400mhz-oc-debian-10-buster-retroarch-1-9-0-mupen64-plus-more-current-build-200903/5088/1):

> Place the SCPH1001.BIN (or whatever PSX bios you use) in the ~/apps/emulators/bios directory. Note that this is now different to what it used to be, ie ~/launcher/sys.py/bios.
