Reyes9 - Yes, max drive and x-port can be used on ALL PS2s for ALL PS2 game files on your memory card.
Even with a patched game - the option file that is on your memory card is the one that takes priority and that is the data that will be shown to you. So the best experience of PES/WE is using a great patch in conjunction with a great option file that is suitable for that patch. Scorpio's option file works great with jonboyo's patch since all the kits are left as default. If you used the pesfan file on your mem card - you'd see the edited kits as made in edit mode and not the patched ones.... to see them you need the kits to be set to default.
There is a way to import an option file into your image after you patch it and before you burn it and details are posted elsewhere. It involved importing/replacing the SLES and OVER files with ones made using the option file data.
elgen - Yes Scorpio's file is very good to use with jonboyo's patch. I've noticed a few mistakes and corrected them to make some kits look better (changing the colours of the numbers and names for all the classic teams as an example) but that is me being a bit picky

Apply the jonboyo patch .ppf to your ISO and then apply the update file. There will be another update released this weekend so you'll have to apply that too. Once you've applied the patches, you can also import the SLES & OVER files from the option file of your choice that comes with the patch update. Or leave it and use the option file on your memory card to correct everything.
I would advise you to back up your ML file as well as your option file. Then transfer Scorpio's file to your memory card, overwriting your option file. Your ML will still be there and when you load your new Scorpio option file, you will see all the lovely patched kits in your game (unless you edited the kit of your own team - in which case you'd see what you made).
