PS2 PAL games that also work for NTSC

Hi was woundering how many PAL games work for the NTSC version consoles as well. no Mods... So far I have noticed Test drive unlimited and Heatseeker, give an option at the begining to switch the mode for PAL to NTSC. does anyone know of any other games.... Also I have a PSP qustion and put it in the wronng forum section it relates to the new firmware preventing me from playing older backups . *www.thinkdigit.com/forum/showthread.php?t=60589
