I can confirm this for track 4; in the very least the sound is off.

I was going to file the same report, with the exact same game. I am simply 
using the demo program in the gme source to extract a wav file, and getting 
some missing percussion on track 9 (my favorite). The Foobar2000 plugin I'm 
using (I think it's foo_gep) plays it back properly, and you can hear the 
proper version here http://youtu.be/CHLsolltIJ8?t=1m2s . The channel with the 
problem is the noise channel, at about 1 minute and 2 seconds. I've checked 
with 0.6.0 as well.

I think it might be an issue with stereo panning.

I replaced Gb_Apu.h, Gb_Apu.cpp, Gb_Oscs.h, Gb_Oscs.cpp with the VBA-M files 
(svn 1231), and now I can hear the percussion sounds. But the sound for 
Castlevania is lower, compare with others game boy sound (i tested with pokemon 
red and crystal). It's about -18 dB.

Other good track to compare is track 12, there is a sequence of percussion in 
the beginning.

(i don't know if it's related, but in track 12 there are 3 seconds in the 
beginning without any music, using Foobar2000, but there is not this in GME)

I can confirm it, but can't do much to fix it aside from finding a more 
compatible implementation with compatible licensing.
