I don't think you can call a ROM with just the music 'PD'.. The music is still (c) Nintendo.

Yeah, we don't need attach roms to download, 'legal' or not. We can use a softlist title in this case, [b]zeldalnk[/b], with the following cheat code for a sound test I just made. I've attached this .xml cheat which you can place in your CHEAT folder and it should appear if you run the named set above. Just select 6 and press ENTER and you can hear it.

This is similar to the way wswan, wscolor has it's sound.. it's high tones are way off at times.. Yet, that driver is flagged for imperfect sound. I wonder why gameboy and clones were give the green light when it's known to be bad in such instances?

1. The sound core doesn't support the Color Gameboy's waves
2. The sound core is OLD MESS code from GNUBoy and other sound emulators around 1999/2000. Sampling issues off the wazoo, waveform issues, and many other problems.

Please keep in mind that a rewrite; specifically one from gbemulator would fix this issue

This was fixed in 0.179, presumably by judge's rewrite of the Game Boy sound core in c3e0ead53494abe36105587fd485e317a788ec5e.

There are other issues with gameboy sound that I guess I need to report.
I'll work on getting examples of games which regressed in sound using gameboy sound (including GBA titles).
