Okay, here is quite possibly a rather pleasant and huge surprise!
It would appear through some initial reports that you can use your edited data – at least kits anyway – in PES2011’s online modes.
Friend of WENB Caniggia from AllsvenskanPES has recently posted this on our boards :
“I can confirm that editing kits and names of teams in your optionfile shows in online matches. It is official.”
There is also a video present on youtube by user azuqeka appearing to show this to be the case on PS3.
Truly wonderful news if indeed true. Rest Assured WENB will be looking into this ASAP, so watch this space.
No confirmation as yet if the other player can see your edited kit data but I am sure some news on that will surely follow in good time.
