Spyro patch problems... Euro/PAL version.

Can anybody help me create a working back up of Spyro 2 and Spyro 3 both Euro / PAL versions.

I have patched Spyro 2 several time only to fine the game black screens when I pass through doors or when the demo starts.

Also Spyro 3 after patching, doesn't get past the intro.

Please help.
