The Multi-Buttons on the Analog Input Pin doesn't behave that good. So I'm adding another C165 shifter to support 8 more inputs, sharing the same clock from the 16xButtons. This will free the Shift button pin. Also, it will allow more key combination for future usage. EG: left+right, or up+down, or anything, as the 8 buttons can be pressed in any order. I will update the specs when possible.
The project is running much slower now, waiting to get more feedback from users first. 
I also have a surprise thing to tell but soon, not right now...
