Notes:
It's the fist MegaDrive pack ripped with
MESS 0.140. (I needed something to test it. :)

Size reduction (vgm_cmp):
  1.59 MB -> 416 KB (25.67 %)

By the way: I used the vgm2mid trimming method,
because the GEMS sound driver makes the VGM
Loop Finder useless.

The two jingles that use the DAC are not
optimized with optvgm, because it slightly
increased the size of the vgm.


I included two versions of "Think Tank",
because of a looping bug. After the first loop
the melody and the second bass instrument go
out of sync (9 measures every loop).
The normal version is looped as it's supposed
to be. This version was hex-edited to remove
some melody notes that were playing where the
loop occours.
The long version loops back after the third
actual loop (based on the bass line). After
some loops it's easy to hear how the music
screws up.

Funny fact: The sound test removes all trailing
zeroes. So "Song 0" doesn't even show a number.
