when playing "dual core" WiiU game, PS3 controllers are not recognised as pro controllers

[giorgionius]

Hello,
I have 3 PS3 controllers and they have worked perfectly fine with all WiiU games (tiramisu+bloopair 0.6.2), except for one game: Dual core.
In this game, you can add up to 4 players (1 gamepad+3 other controllers). However, when adding 2 or 3 players with PS3 controllers, only the first one is recognized as a pro controller (then you can't use the other 2) . Also, during gameplay the only PS3 controller recognised does not work properly (some buttons are not responding).
