I wish I could still get a Nanoloop 1.5 cart. I heard the extra channel was nothing to write home about, but I would have still liked to check it out.
I had a 1.5 cart before i gave it to matt.
Its alright, not really my cup of tea haha

Well, if anyone has a YM2413 that they can donate to me for science, let me know.

It is a bit of a different beast but I have a YM216 you can experiment with if it would help?

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.

that YM2164 would be even better imo!
Why not go the whole hog and stick an OPL3/4? 
Size issues?
Edit: Yep. Beat me to it ^^

is there really any limit on the size of a gameboy cartridge?

I'll gladly snag some off eBay and have them sent to you if you think this project could actually go somewhere. PM your shipping info etc if you're interested. 
EDIT: Here's 10 for $38, sounds good to me: http://www.ebay.com/itm/10pcs-YM2413-DI … 4165ac3ec4

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.

Ha, it would be crazy to expect it! I just want this idea to be explored since you seem to have a starting point in mind.

It looks like egr might well have you covered but if you get stuck, is the chip similar to the VRC7?

If it is, I can probably rustle up a copy of Lagrange point or two?

Is it possible to stuff a SID chip in the GB? dreams come true! ;D
Thanks for even trying this idea nitro!
