Great work! Maybe you can add an option to use the 'heightmap' method described by Justin in his blog post. And maybe let users add their own palettes? :)
Figuring out how to add game boxart and screenshots to my recently-relaunched MIDI and chiptune player: https://pixeltune.org/
It's a fun challenge, because I need to figure out how to reliably determine the matching game for files like /pub/johnny/midi/games/sc2kmenu.mid, and also to show them in a way that fits nicely in the UI.
Yes, as I mentioned in other comment, Pixeltune applies a reverb effect on some of the cores. There's currently no way to turn it off but there will in the near future. :)
Oh, yes. That's because the Famitracker port I'm using[0] is a bit old and doesn't support the newer .ftm versions. So in case the player doesn't support a given song, there's a fallback to using FTMtoMID so you can still listen to it.
This was all done before I ported Furnace Tracker (that also supports the .ftm format) so I might just use Furnace for playing them. I have to check whether it can play the newer .ftm versions.
