You dont need to use AFS with an option file - just replace the one you've got with an updated one.
The option files usually saved in your documents/konami/pes2009/save
Got it sorted man, thanks. All the demo patches I found required AFSeditor so I assumed that final versions would be the same. But I guess common sense would say you could merely replace your own option file save folder with another persons and have all the editing get transfered. This is my first go at PES on PC so I'm a tad ignorant at the whole option file thing.
