> The Portal song in particular stands out, the only other game that I know of that tries to do voice playback is the Pokemon Yellow Pikachu cry you hear at the beginning of the video, and it's rough at best. Bionic Commando has a few speech samples. There's a game called Cannon Fodder (an Amiga port, I think?) that opens with full motion video, with matching audio. They're both pretty rough, quality-wise. The explanation of the demo video has a good explanation of how the wave output hardware works, and how they got such high-quality output. I think it's a combination of bad timing and non-use of the volume-shifting tricks that kills the audio quality in commercial games; if I make an emulator dump the samples to file and import it into Audacity or something, the output is much clearer (about what you'd expect for mono, 4-bit samples at 10KHz or so).
