@bucky, I looked over Blargg's source and I can't find a way to easily turn off channels, but maybe we can get him to make the modification. It looks possible, just probably something he should be doing.
@ui, yeah sure, it's available for use on your site. Once things firm up a bit, I'll make a tutorial on how to add it to your page. Or, if you're ambitious, just check the page's source code. There are no other server file requirements beyond the .swf file.. and an nsf, of course.
Ok, so some updates. The track select buttons are now limited to the number of tracks. It also displays the Title of the song, read from the .nsf.
