A Little Unclear on Patching

[Yochana]

Hi,

After purchasing my Son a Playstation 1 and Modchip for his 11th Birthday, I now have to learn a little about backing up his games, especially with younger brothers and sisters around. I have downloaded and installed CDRwin, and am following the tutorial for copying a CD (using CDRwin) available at PSXCopyworld, but am a little unclear about how you know whether or not a Patch needs to be applied. Here where I live, all Playstation Games are PAL, so, using Harry Potter as an example, how can I know if a patch needs to be applied? I see that there are 3 patches available here at GameCopyWorld for the PSX version of Harry Potter, but they all seem to be related to NTSC - PAL, which I gather is unnecessary in our situation.

So, if there is a helpful webpage somewhere, or if someone is willing to clarify this for me, it would be greatly appreciated!

Many thanks!
