Go to the site above and search the page for Tony Hawk, you should see some hexadecimal instructions that when put in a hexadecimal editor like HxD you allow you to create a .CONFIG file that will fix all the problems that you are having, this especific config fixes all Tony Hawks games and Gun. I recommend you to search and know more about CONFIG files and the way that the PS2 emulator runs under the PS3, NFSU2 is another beast entirely, but some progress has been made though, this is an awesome forum for PS2 emulation discussion and CONFIG file creation, in the end of the page there is a experimental CONFIG for NFSU2 PAL version. https://www.psx-place.com/threads/compatibility-list-ps2-on-ps3.1306/page-154
