That is no surprise, given my choice of sound driver.
The track was produced in 20 minutes, so it was rushed. Still... the tracks were short. Shorter than you expected, but I produced the whole thing.
Tell ya what. Over at the Famitracker forums I posted a test .NSF file that I specially modified so that perhaps it satisfies the requirements for compatibility with the TNS-HFC3. It's really just segmented DPCM samples, but the idea is that if it runs on hardware (it's more than 32KB and it has a bunch of DPCM), then this track can be safely converted. I have a special version of the converter on hand (I have the it2nsf source on hand, so I hacked the C++ file to my liking) so that the process is automated.
This song is officially the last song ever produced on the iMac G5.
