PES 2013 Nike MV IX pack by YB (Yevan91)
To insert boots in PES you need to copy file from dt0c in kitserver dt0c
Pro Evolution Soccer 2013\PESJP 2013\pesjp\img-Jekney patch
Pro Evolution Soccer 2013\kitserver13\pesedit\img-Pesedit
And yes if you want to insert the preview, open the file dt0c unnamed_2157.bin possible through Game graphic studio or via Img explorer, rest is simply replace your desired preview.
That’s all, have a nice game.
If you use my boots texture, please give me credits.
