Hi, sorry for the long delay.

Thanks for these patches, I didn't even know about the Pico before you created this ticket, and VGM dumping support is nice. After a quick review, I'm willing to include them in DGen/SDL, however I think they need some modifications:

• Split VGM and Pico support in two different commits.
• VGM documentation should be part of the VGM commit.
• Each commit should contain your signed-off-by line, a title and
  a more complete description of what it does. See previous commits.
• Please remove trailing spaces (though I can fix that later).

Since I haven't tested it yet, how well do Pico games run in DGen/SDL?

Thanks.
