What buffer setting should I set for CloneCD?
 

I have a p3 600 with 256 mb of ram... the default buffer setting is 22.71 mb and 8.37 mb... should I change it?

Also, I have a HP 9100 series burner, is that fully compatible with CloneCD?

Thanks in advance. :)

EDIT: I can burn just fine with CloneCD... but some games still require me to use a crack, Civ3 for example... are there any settings I should enable/disable?
