I've selected the ISO, but it just says "Playstation 2 Disc" and re-enters the browser when I select it. I know this sounds stupid but how can I play the game exactly?
Please post the contents of the emulog.txt file after the problem occurs. The file can be found in "My Documents\PCSX2\logs" for the installer version or in "PCSX2\logs" for the portable/binary version.
Please make sure to enclose your emulog in code tags like so (remove the empty space on the closing code tag!):
[code]
Pasted emulog goes here
[ /code]
Do a fast boot instead of a full boot.
