Picade / Icade button layout problem. A Guide to Building your Picade PDF anyone?

Hi,

im looking for a PDF File of the Picade Guide since i bought the PICADE X HAT kit and im struggling with my button layout :) The Icade has eight buttons on the Panel instead of six and now im some kind of lost.

Especially im not sure about the two on the side and the two in front of the Picade :) Exit ? Ent ? Select ?

Any hints?

Thanks in advance for your help.

Best from Germany,

Simon
