After installed Free McBoot and HD Loader, I know that I can use Harddisk to play PS2 games and ignore the DVD drive ever.
However, I know some games don't support HDL or even I just wanna play games with DVD, like a PS2 which haven't installed any apps like Free McBoot or HD Loader, can I still play PS2 DVD games like an original PS2??
P.S. My PS2 is fat PS2.
