What to do when Bios Rom is empty in pcsx2 o9.7?

If the BiOS ROM is empty in PCSX2 0.9.7, you'll need to ensure that the BiOS files are correctly installed. First, locate the BiOS files from a legitimate PlayStation 2 console, as using pirated BiOS is against legal guidelines. Once you have the BiOS files, place them in the "biOS" folder within the PCSX2 directory. After that, restart PCSX2, and it should recognize the BiOS files.
