Virtual Boy Wario Land

Kazumi Totaka has a very interesting style that
mixes music and ambient sounds. This results
in some tracks consisting entirely of SFX.

It also made some of the tracks hard to loop
due to desync'ing channels. The worst track in
that regard is Level Theme 5, which has 4
entirely different loop patterns playing
simultaneously on the 6 channels.

There are several unknown tracks. I assume they
are unused, because I couldn't find any write
to the memory triggers with their song ID.

Apropos tracks - an interesting fact is, that
some of the jingles (e.g. Lose a Life) begin
with silence to let sound effects play.


The track order and song titles originate from
Blue_Kirby2's VB Wario Land gamerip.

Hacking Notes:
The sound engine features 7 different addresses
that trigger certain SFX and songs.
The following list contains the address of the
memory trigger, the offset of the pointer list
in the ROM and the number of valid IDs. IDs
begin with 01.
The "jingles" lists seems to be unused.
