Place your PSP ROMs in
\.emulationstation\roms\psp
There isn't really a BIOS per se but you may bet a warning saying something along the lines of ppge_atlas.zim missing but I just ignore it and the game still works. You can get the ppge_atlas.zim file from the assets folder that is in the download file for the original ppsspp here: PPSSPP then place it in
\.emulationstation\systems\retroarch\content
