This is just to archive/document a test I made in 2012 and was still available at
this famitracker forum thread.
It's just an NSF with three tracks:
- song 1 = read-mode MMC5 PCM
- song 2 = write-mode MMC5 PCM
- song 3 = 2A03 DMC reference
On each it plays a short looping voice sample. Source code is included.
