It actually looks like LedBlinky isnt picking up game start but I can see nothing wrong. Game select is not sent from the screenaver but game start is.
You say it is only GameEx that has changed and it used to work so it is on me but I really cant see anything, sorry, orther than game run/start isnt being sent to LedBlinky but I can see the code in GameEx is still there.
You say the wrong commands are sent but can provide no useful detail. Not sure what I can do right now. Sorry.
