I have not had a chance to update my firmware yet to test, it works ok on the 13/9/13 firmware version.
I'm not sure if there were any major changes in the last firmware update to break compatibility.
I will update my firmware tonight to see if it works.
The sound is buggy in this version, it was my first attempt at compiling for the zero.
I am pretty much a noob at using linux and compiling software.
I didn't want to keep pestering devs to port it, so i thought i would have a go at compiling it myself!
