Well it's alot simplier than I thought it'd be
Just start with a fresh iso of the pes5 retail version. Then apply any patches you want like normal. But make sure not to import any of the sles files from any patches as most were made with the beta version and it won't work with the beta sles.
Now after you'll more than likely need to rebuild your iso. So just use nero burning rom to make a iso image instead of burning to disk.
Now you will need to patch the the dnas onto the disc, but as kezz has already said it's illegal so we can't talk about it. So just search on google and you will find the answers.
Once this is done just boot the game with swap magic and voila a patched pes5 online
