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. =)
