After reading over the Wikipedia page on that chip it really does seem like the perfect candidate. Tiny, just enough features to be useful, has a DAC already in it. \o/
Actually, thinking about it further, other (surface mount) chips could be used as well, if you put them on a PCB and put that PCB on top of the CPU. There should probably be enough space there to accommodate the chips. However, this would require a small custom PCB and SMD soldering skills. Anyone who can hold a soldering iron should be able to install a YM2413 with a couple of wires, and put it in the right side pocket of the DMG case.
The bad aspect of the chip is that only lets you define one completely custom instrument at a time. (You also have 15 presets to choose from.)

It was used in Sega Master System, (in some games) and the NES VRC7 chip is a derivative of it. For inspiration:
If it can be listened to, it can be downloaded. If you wanted download protection to be disabled, you would need to not only remove the link, but to other tricks to keep actively keep the file from being downloaded, such as trying to detect when file is downloaded by Flash, and when it's downloaded directly by the browser. In the end it's a futile struggle. If you are concerned about this, only upload one or two tracks from an album.
Farbrausch recently released all their stuff as open source lately anyway. I don't know if there was an open source demoscene movement before that, but I'm sure the trend spread after they did.
Is it possible to stuff a SID chip in the GB? dreams come true! ;D
Thanks for even trying this idea nitro!
Nah, what I'm talking about at this point is an FM chip that's small in size. This wouldn't quite be a SID, but still a new flavor compared to the boring regular Gameboy sound channels. But in general, the SID chip can be interfaced by "any" CPU. (Assuming the CPU is using +5V logic and is not faster than the SID can handle.) In the early days, before the C64's success, the SID was marketed to external companies as a general purpose sound chip, but apparently that was never very successful. I'm guessing MOS Technology (by this time owned by Commodore) later stopped trying to sell it to 3rd parties to keep the competitive edge of the C64.
Lazerbeat, once again I must politely decline the offer. For one, I think the VRC7 is too big to fit a DMG. But I would also feel bad about butchering rare (?) game cartridges. If this is done, at least they should be placed in NES flash cartridges. And/or use Tiny Toon Adventures 2, which apparently doesn't use the sound functionality in VRC7.
I can't guarantee that I will have this working overnight if I was sent a chip, but I do have a theory for how to make it work. (For those who may be interested, it involves using the echo RAM space as register space for the sound chip.)
ant1: Depends on whether you want mold your own cases. Also, there's a slight difficulty using through hole chips in a GB cartridge since the PCB normally lies flush against the bottom of the cartridge case, but a through hole component take some extra space under the board for the chip legs and the solder. You could get around this in various ways, but extra work.
Thanks for the offer Lazerbeat, but the YM2164 is less suitable for this than the YM2413 because of its size, and also because requires an additional external digital to analog converter chip. So it wouldn't be practical, if even possible to fit everything needed inside a DMG. YM2413 is smaller (even if more limited) but has everything built in.
