Actually, I realize the extra resistor was a 4.7k, for those who might be in need of that fix.

Re: Arduinoboy question (7 replies, posted in Nintendo Handhelds)
kitsch: Actually, you've misread what he said. He said he had 220 ohms but not 270 ohms. 220 ohms is used as the limiting resistor while 270 ohms is used on the secondary side as a pullup. I once played around a lot with that to find that adding a 1.2k (IIRC) resistor from pin 7 (the unconnected pin) to ground could improve signal quality when stealing power from over the link cable. However, I didn't document the tolerances for the 270 ohm resistor. My bet is that 220 ohms will work OK.

In the name of science, I tested if it was actually just a shop, or a recreation.
I got the highest quality version of the original art, and scaled it down to 100x100 pixels (the resolution of the Kind Of Bloop art). This is what I got:
So the Kind Of Bloop art is definitely original, not just a modified picture. Unless there's some insanely awesome filter nobody knows about...
I know it's pretty obvious that it isn't a shop, but I just thought it would be nice to see how different a shop would look. Fairly different, it seems...
You're missing something, the color reduction. It's possible that with color reduction, you could come somewhere close to the Bloop cover, although you'd still need a lot of work. That would just provide a convenient starting point. I think the artist at least used the original as a guide below the canvas if you look at how similar they are in shape. See below, where I superimposed the Bloop cover over the original. I applied an edge filter so you can see the original better.
Certain details match up perfectly, which is what leads me to believe that he drew the cover over the original. Look how the lighter skin tones match up almost perfectly in the two images. Same with reflections on the trumpet shades on Miles' jacket. What does not match up perfectly, obviously, is the pattern on the tie. 
(And no, this does not change the legal argument in the slightest. I'm just trying to objectively describe how I think the cover was mde anh why I think so, for those who are curious.)
The original comparison for reference:

Question: How does the bounce-back for select/start work? I suppose you need to have rubber pads under sel/start to make the button go back after you press it? Do sel/start feel comfortable to push?

Posted by a grumpy facebook friend of mine:
So the guy is mad he got sued for copyright infringment for the creation of an unlicensed derivative work of the photo? Fair use is an "affirmative defense" which, saving you the legal mumbo-jumbo, means you buy-your-ticket-you-take-your-ride. Even if your fair use defense is a "winner," you have to spend lots of time and money litigating it. The guy clearly knew he could get a license (as he did to cover the songs), and shouldn't cry foul when he takes his calculated risk with the cover and loses...
thoughts?
Andy addresses this very point in the blog post:
Andy Baio wrote:
And it's worth noting that trying to license the image would have been moot. When asked how much he would've charged for a license, Maisel told his lawyer that he would never have granted a license for the pixel art. "He is a purist when it comes to his photography," his lawyer wrote. "With this in mind, I am certain you can understand that he felt violated to find his image of Miles Davis, one of his most well-known and highly-regarded images, had been pixellated, without his permission, and used in a number of forms including on several websites accessible around the world."
Your friend is right as far as facts go. Fair use defense can cost you a lot of time and money. Counter-questions: Don't you (or your friend) see a problem with legislation that can be used for basically extortion in the way that copyright laws can? Is fair use of any real significance, if you need deep pockets and expensive lawyers in order to use it as a defense? Do you not see the flaw in the legal system?

I've uploaded the file here. Feel free to use this is the official link if you want to. It's not going away anytime soon.

I also changed the filename to include the date of the files. Might prove handy later if there ends up being later versions. And since you finally released this to the public, I also uploaded my own version with hand-routed traces for the RAM chips. Didn't want to make it public since I wasn't sure if you wanted this project to be public yet.

Re: Change gba clock speed with BIOS settings? (4 replies, posted in Nintendo Handhelds)
Do you have a source for the statement?
As far as I'm aware, you cannot change the clock frequency in software, but you can change the so called waitstates for ROM accesses. This basically means that the GBA waits fewer clock cycles for the memory chip to output the requested data. This makes the program run slightly faster but if the memory chip can't cope with it, you'll get invalid data and the thing will crash.

Re: Do GameLink receptacles exists in the wild? (6 replies, posted in Nintendo Handhelds)
The problem with building an ArduinoBoy using a link cable socket is powering it. If you're using a big fat 'duino board with a shield, that may not be a problem, but if you're building a stand-alone unit, you'll want to do the pin swap mod so you get power supply from the Gameboy. You can't do this with a socket, as a standard cable doesn't carry the power wire.
And even so, link cables are cheap. Buy one and cut it in half. No big deal.
Another thing, why do you insist on mixing top and bottom layers as much as you can? Try to keep everything to the top layer so people who make PCBs at home can make a single-sided board. So far, the design can trivially be made to use only one side.
Why the top and not the bottom side? Because the first thing you need to consider for a single-layer shield design is connecting the pin header. You can't solder the pin header to a single-sided board if it's on the same side as the copper, since the plastic would be in the way.
Most of the components, yes, including both the opto-coupler and all the passive components can be placed on top and soldered on the top. The one thing that can't is the MIDI jacks. These would need to be pointing down and possible moved out as not to collide with the 'duino main board.
