Do these games need patches??
nfl extreme 2
nfl blitz 2000
Problem 1: I have read about the patches and I have a psone and I need to know what patch to use to remove protection. All the patches I see in game copy world are ntsc 2 pal.

Problem 2: some of the cd's dont show their name on the drive letter. e.g. my cdrom drive F: just shows F: and other times with other games it shows the name F:slus_123. Is that some kind of protection thingy too. Please help greatly appreciated.
