the SCPH is the bios bin that you need, the others don't seem to be needed, I don't have them

ah ok. But in the log of PCSX2 apparead a screen that say: erom not found, rom1 not found, rom2 not found...

as saiki said they're not needed, but you can include them if you want to (or if those messages bother you ) (they would bother me and that's why i have them included )

EDIT: and because i like my stuff to be perfect

You should have a full bios for maximum compatibility. It is not proven yet but missing rom1 and (less) rom2 files could lower compatibility.
If you dumped your bios with the latest dumper from our site,you should rename the .rom1 and .rom2 files to rom1.bin and rom2.bin so PCSX2 recognizes them

thank you to all for the info guys!
