@petrockblog Thanks for the confirmation.

By the way, I received the ControBlock that you gifted me with. I truly appreciate the gesture. Thank you so much!!! I will definitely put it to good use.

I never got any response from @petrockblog on this....so I'm asking again, are there diagrams that we can look at? Also, how about a Parts List? Some of us are having deficient power when the ControlBlock is used. I know that a transistor (Q1) switch supplies power to the PI using the GPIO pins. The question is, what is the max current that Q1 supplies the RPi with? Is it 2.5A or much less? Is this a constant current or fluctuating current? Without a diagram and parts list we are constantly guessing where our issues come from.

@x5PUDx If you already have the latest Retropie version build, then doing an update using "update all installed packages" should not mess up anything.

@ortsac hate to hijack this, do you have pictures of your completed project? You may have built exactly what I need to build myself for the misses. I am looking to also emplace a Pi3 into an authentic NES console, for use just for NES and SNES emulation. I would like to bounce some ideas of you if possible as well as get some feedback/guidance of any issues you may have ran across.

Awesome! Thanks for the reply! Keep up the good work!

I know this topic is a bit old, but I answer never the less:

The ControlBlock is stackable and supports to four players! This feature was introduced with a recent update.

I hope that points you into some direction.

Perfect, thank you for confirming.

@UDb23 - Thank you! I'll snag the MAME version of Contra and see how that handles it. I appreciate you pointing me in that direction!!!

@skcradle Glad to hear.
