I was just wondering, does anyone ever mess around with the ps2 bios settings? I noticed that theres an option when you press /_\ triangle on the main menu for "version" and then press it again on the play station driver (I myself have 1.11) there are 2 options one for disc speed and one for texture mapping. They are currently both set to standard, but they can be changed. Does this matter and if so would it help to emulate things better or should I just leave it alone on default? Just curious...
Yes it is.
For clarification, the options helped Psx games look slightly better and run slightly faster (but with some side effects in some games). That was on the actual PS2. Pcsx2 does not emulate PSX games so the options are ineffective.
