Wayne : don't worry, it's just the last version of PAL patcher I want to send. It's not yet on DC Copy World, and it isn't illegal, I think. But thanx for your advice.
Lazarou : just check all the options you want PAL Patcher to look for (for example, 60 -> 50 Hz), select your image (open your CDI file) and then click "Search". It will list all possible patches it can find. Then, you'll have to select one of them in the list box and click on "Patch". That's all.
