Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Mario does not work for me (yes exactly this version from your link, when I press X on usb keyboard), screen gets black and I am back in the menu.

BUT: I'm glad I also tried Zelda. This works with "X" key AND the most important thing you wanted to know:

SOUND works via HDMI! And it is great, no glitches, perfect quality. Imagequality is also perfect and rock solid (I tried bending the breadboard wires wildly) - no problems. Even played a round Zelda  

Cool!

Greetings
Daniel
