Ok let's try another thimg , try to use psxfin or psx1.13 (are the same emulator) the games run as in a real psx so there are few graphical enhancements but is a good emulator to start since you don't have many options to configuure.
If you can access my page (seems to be problems to accces sometimes) you can dowload the emulator and see the guide and
these is the official page http://psxemulator.gazaxian.com/ Note: you will need a PS1 BIOS image (not supplied)
