I've chosen to leave behind the #libmikmod for DS despite I knew mikmod for a long time and go for a somewhat-obscure, custom homebrew developed library called #libntxm

(I still have to dig into the community-maintained revival of that library, though)
Next #ndsdev milestone: tweak the #libntxm #trackedmusic player used in my game engine so that it could use shared tracks and samples (for common sound effects) while we have per-world background music.
Common SFX have been just shrunk to 200KiB. Expect 500-700KiB per background track.
