I had problems playing the entries. NSFplay didn't work and DeliPlayer might have not been properly playing back. My entry sounded different (the screams being cut off, while I had not used the note cut :-/). What's the best way to play back on Windows systems?

...NSFPlay. There might be something wrong with your playback setup.

I had a problem playing a couple of entries in NSFPlay, so I used Foobar2000.

Ah yes, Foobar2000 with Game Emu Player component (http://www.foobar2000.org/components/view/foo_gep) works like a charm!

If anyone one with the right privileges would like to update info on the info of formater nsf and nsf+, many n00bs after me will be happy.
