Also, if there are any older docs on here that are known to be horribly
inaccurate to the point of being useless, let me know so I can kill it.

- Skate or Die 2 (title theme) Recorded by Memblers, through the audio output of an NES. This Rob Hubbard tune uses raw PCM output ($4011) that few (if any) emulators play correctly.
- Comic Bakery Recorded by Chris Covell. This is an MP3 of how this cover of a Martin Galway song plays on a real NES (The one in the Stars SE demo). It doesn't sound too good, due to some scarcely documented um.. features of the NES's sound hardware. Since it does a great job of highlighting these features, it may be be useful for emulator authors who want to improve their sound emulation accuracy. This MP3 is in stereo, the square waves are in the left channel, the triangle is in the right one. The noise channel isn't used. If you're wondering, these features were compensated for in Bananmos's newest sound code (as used in Solar Wars), and it is now 100% cool on real NES. =)
