PES 18 Serie A Referee Kits Pack by Hawke
To use this mod correctly you need to create a separate UniformParemeter.bin, for this you need to use UniformParemeter Builder 2018, I made a tutorial for this here: https://pastemod.com/tutorial-by-hawke/
The best way is to make a copy of your Team folder ( the one you use to make a UniformParameter.bin ) & name it Serie A Ref Kits and then add my Ref Kit bins to that folder and create a new UniformParameter.bin. Now create a Cpk with my Serie A Ref Kits & your new UniformParameter.bin. This way you can load it via DpFileListGenerator as an add-on when playing Premier League & then when you disable it your old UniformParameter.bin will load enabling you to revert back to default Ref Kits when not playing Premier League. Then just remember that when you add kits to your patch/game in the future to make 2 UniformParameter.bins..one from your main kits team folder & one from your Serie A Ref Kits team folder add-on.
