Notes:
Pack was made using M1 v0.7.9a1 VGM mod and
"mrheli" ROM set. The music appears to be
identical with that of the localized version of
the game, "bchopper".

Track titles are from the "irem RETRO GAME
MUSIC COLLECTION 2" (KDSD-00449) OST, where
applicable.

Note that all of the songs are using only up to
four of the YM2151's eight voices, making room
for lots of simultaneous in-game SFX.
Similarly, the DAC functionality present on the
Irem M72 system board is not incorporated into
any of the songs, instead being claimed for
certain sounds (such as explosions).
