These logos are depressed into the ceramic chip, so it cannot be part of the printing process.
Was thinking it was a security feature for Game ON as someone would have to duplicate the ceramic mold, rather than just printing the logo on the chip (I use the term printing very loosely as I know its much more complicated than just printing).
I would consider it a mold just like H&C and RHC as it is manufacture specific. IMHO

Also, thanks for the update on the update
