With a 74hc04, no. You need a DPDT switch for that. You could use a 74hc86 chip with a SPST chip. Described here:

Ok then. I always thought that the sound differences between DMG and MGB are caused by amps and other stuff and not by CPU. Guess there is no actual data on this anyway...
There is some data. For example, Herbert Weixelbaum's sound comparison.
http://www.herbertweixelbaum.com/comparison.htm
There's also an interesting (though not 100% confirmed) theory about the DACs of Gameboys described in the GBSOUND document.
PARTIALLY VERIFIED:On older versions (pre-DMG-CPU-05?) of the DMG, the scale
of
the DAC used on the various channels is semi-logarithmic instead of truly
linear. Later Gameboy models (MGB,SGB,CGB,GBA) used either better pull-up
resistor/capacitor and/or analog output DACs, and are almost perfectly
linear.
(Thanks Jeff Frohwein)
Here are some scales for demonstration:
TRUE Logarithmic:
0---------------1--------------2-------------3------------4-----------5----------6---------7--------8-------9------A-----B----C---D--E-F
TRUE Linear:
0--------1--------2--------3--------4--------5--------6--------7--------8--------9--------A--------B--------C--------D--------E--------F
Semi-Logarithmic:
0-----------1-----------2-----------3----------4---------5---------6---------7--------8-------9-------A-------B------C-----D-----E-----F

Re: Beginner MGB questions (27 replies, posted in Nintendo Handhelds)
It's the same CPU architecture from the software's point of view. GBC obviously has extended functionality while the functionality is same in DMG and MGB CPUs. But the CPUs are quite possibly made with different manufacturing processes, which could influence the sound. There are of course also other differences in the design apart from the actual CPU chip. This includes the voltage regulator and the audio amplifier (assuming you're not using a prosounded unit) and just the fact that the MGB and GBC are using two AA/AAA batteries instead of four.

Have you tried cleaning the contacts? Internetz says that baking soda will get rid of the corrosion.

Did it ever happen again? Did you write down the values? If it always happens, are the values consistent?

This model was a consumer product, not a development product so it's not very likely it would contain prototype material.

Only the top 1% of apps on the app store actually make any money at all. Millions? You're dreaming. We've made infinitely closer to $0 than $1M. We do it because we love it. We're just as broke as the rest of you plus we have no musical talent or training, so we have to humbly come to you and get mud thrown in our face.
We get it. You're poor too. But the problem with the original proposition was no payment AND exclusive rights. If you want to play nice, pick only one of the two. There was not even a mention of due credit to the artist. The original legalese didn't read "help a brother out" but "if we do make it big, we don't want legal trouble".

Come on, don't be so harsh on him. Is it too much to ask for to have someone work for free and then give away all their rights?

The real spelling is fukuoka (well, at least when transliterated to the Latin alphabet) and the added C is obviously a play on a certain English language curse word. The question, rather was why they left out the second u when writing it in the special way.

you know im noticing you put a jumper wire between what looks to be a spot for a .1uf cap... it looks unnecessary.
That's not a place for a cap. That\s a place for a jumper wire or jumper pin for optionally powering the whole device from the Gameboy, through the link cable, if you have no other power source like USB.
But, like I mentioned, I would first solder all the pins of the pin header, and also to check if the microcontroller chip is oriented correctly, no joke.

awesome! question- does anyone no why these guys and like usk dont place the letter u when they spell fuckuoka? or am i missing something?
I think the second u is almost silent in practice. And also, fuckuoka could be read as "fuck u oka" and maybe they don't want that.
