i've searched already on google and also here in the forum. But my questions are still not answered in the way i liked to.

So here we go:
First of all i have one Cube with WKF/Swiss, one with a Qoob Pro/Swiss and one with a Xeno GC and Swiss on SD2SP2.
My plan was to desolder the WKF and solder a Pico in. Or does the WKF has any advantages over Picoboot? I've searched the forum already but i doesn't find anything about it. Is the compatibility the same or does the WKF provides a better compatibility?
There should be no difference in compatibility between the Qoob Pro/Picoboot/Kunai or Bootdisc if the games are booting from SD2SP2 but I'm really unsure about the WKF because it's an ODE. Maybe someone can light me up?
Thanks in Advance and sorry for my English!
