Patching probs

[manuman]

Hi,

I have tried copying a couple of games (using CDRWIN v4.0a), and then applying .ppf patches to them using PPF-O-Matic v3.0.
Everything goes fine and then I write the image on to the CD.
When I try and play the game, it acts as if it is not a PSX game, for example, an audio CD.

I have tried this with a couple of games, including Spyro 3 and The Italian Job.

Are there any settings or something that I should be changing??
I'd appreciate any help,

Thanks
