Notes:
Well, here is the pack I used to test ES5503
support in VGMPlay.

The music is .... okay, I guess - except for
the fact that there are wrong notes the
developers didn't fix.
The Level 0 song starts with one.

There seems to be an excessive sustain to
some of the notes. (like the piano bass)
This, combined with dynamic channel allocation
is also the reason why I didn't include a
looped version of the title song.


Size reduction:
1. vgm_sro: 4.14 MB -> 3.60 MB (87.0 %)
2. vgm_cmp: 3.60 MB -> 1.04 MB (28.9 %)
Total: 4.14 MB -> 1.04 MB (25.1 %)

I logged all songs from the title screen.
The PlayMusic routine is at 02C033, so I set
a breakpoint there and changed register A to
song ID I wanted to play.
The song pointers are stored at 02C21E.
