Hi Martin,
The issue with Kong on 6.00.02b11 is most likely the sheer size of the heap/free RAM.
I wrote a simple "play modfile, play stop, play flac" and printed heap size.
You can clearly see that 6.00.02 has 4kbyte less heap.
And AFAIK, there is no memory leak, memory is returened with PLAY STOP.

101632 heap
76800 play mod
101632 play stop

That is also shown if you type "memory" in both PicoMite versions (124k versus 128k RAM).
That should at explain why Kong does not run on 6.00.02.
Playing FLAC uses 42kbyte heap
Playing MOD uses 24kbyte heap
So playing FLAC may not be the best option here. Is there any way you can convert the FLAC to MOD ?

EDIT: so PLAY FLAC combined with FRAMEBUFFER L uses 80kbyte RAM/heap of 97 available in 6.00.02b11. Only thing to become more efficient is use fewer strings, fewer arrays (these eat heap) and use more normal variables (are in the 28k reserved RAM area, not heap).
