I wrote it wrong in the post. They are currently in the RetroArch>Documents>RetroArch>system folder. I only pasted the 3 bios files I needed for the OS X version of RetroArch.
I just dropped all the bios files to see if it would make any difference.
For the PSX files, do I need both the bin and cue file? I have them as separate files currently, which is how it works on the desktop version.
CORRECTION: I made sure to use the PCSX Rearmed Interpreter core and it is working! WOO
