Runs great on Mame. Did you test on a real nabu?
I checked the version of NABU-LIB.c you have in this zip file against the one I am using and besides the setPatternColor() function; there no other differences.
I also tried with the version of snake.c in your zip file and it worked perfectly in Mame, but when trying to exit the game on a NABU machine it crashed and the check light came on and didn't turn off.
I wonder if there is some minor difference between the handling of messages from the Nabu over serial vs those arriving over TCP.
The annoying thing is it works in Tetris. It also works without issue in the following sample app I made to try to reproduce the error:

Very confusing.
. I have a plan to make a website that allows ppl to upload programs that get put online - but I’m not sure how to filter users and programs yet. Could lead to some real big messes.
