Thanks man! I appreciate it!

Awesome! Let me know if you run into any problems and I'll do my best to help!

Hahah yeah man. I've been wanting to do this for years so I've had a lot of ideas. I just figured it would take too much time.
So I've got these 5 little prototypes on the way then after that I'll be making some Shield Boys(got the latest file) and some LSDjMC2s.

Haha 5 damn crazy. Well enjoy! Hope you grabbed the latest ones with the MIDI OUT fix? If not, it's easy to fix with an adapter of some sort. The all-in-one board I'm making I'm rather excited about.

I plan on using a few of them inside a 1U case that also houses a USB-MIDI bridge (GM5x5x5 specifically) to connect everything. That way I can just have USB out the back, and some connectors for the GameLink cable in the front along with maybe an extra MIDI I/O set or two. Should be really nice to keep things nice and clean at home and for live shows.

Hey man! Thanks so much for all this info. Can't believe it was so simple and right in front of me! I've got 5 prototypes on the way!
I grabbed the Eagle CAD files so I should be making one of these pretty soon!

Finally fixed the MIDI Out issue. Turns out pins 4 and 5 were swapped on the layout. I have updated my build doc with the latest board revisions to remedy that. A simple fix for current boards is to just cut a midi cable and swap the wires, or make an adapter cable that does the same thing.

I use DorkBot for my printed boards. It is awesome in every way - generally inexpensive, fast (for crowd PCB fabbing anyway), easy to work with (just send in your Eagle Board file), you get boards in groups of 3, and they offer the boards in purple As I recall, having the ShieldBoy board fabbed cost about $30 (or $10 a board since they come in 3).

If there was enough interest, I wouldn't mind doing a medium scale run (about 25 boards). I'd prefer to either remove or fix that MIDI OUT though before I did that. And I still want to make an all in one design (where you just pop in the AVR chip from your Ardunio and you're off) if that's something you'd rather wait for.

Do you sell the pre-printed board or is my only option to print it myself? Do you sell it in a kit or anything? I really love what you have going on here but I honestly don't have the time to go and print a board. Building and assembling is no problem.

Since some folks were starting to build this thing on their own, I thought it would be a good idea to go ahead and update the files and layout on our build page. I still haven't fixed the MIDI Out issue, but I'm actually thinking of doing away with that entirely when I build the all-in-one (or leave it as a pin-header) since I never use it and could save some space by not worrying about it.

I'd like to figure out why it doesn't work on the ShieldBoy at some point. It's not a huge priority but I do plan on figuring it out one of these days

Doh sorry didn't see that original post, but I have responded to it with my thoughts. I think it might just be a simple case of needing to power the ArdunioBoy correctly (the 5V jumper is bridged and it shouldn't be as you have no 5V input coming from the GameLink cable).

Hi, I recently built your shiled, thanks in advance!! good clean work, and ver nice for sharing it

I wrote a post in this forum but nobody seems to answer, so I thought to ask "the creator" of the shieldboy instead

this is the post I wrote:

A picture of the interface:

Basically I cannot comunicate with the GBA. I think should be something to do with the link cable when using the flash cart, as the interface is properly built... I´m using a cartridge M3 for Gameboy with a mini SD card, which allow to play ROMS and certain ebooks, videos, music, in the gambeboy advance.

Also using MEGA 2560, any ideas if I should adapt the Arduino sketch to load in MEGA?

Any help would be apreciated!! Thanks! and keep up the good work.

Doh', correct!  I was thinking it was a combo with the arduino for a sec.  My bad!

As in physically right? I did find this and it actually indicates that the pinout is correct if I am reading the top-left diagram correctly.

There are shields for arduino pro mini as well. I've actually been working on something like that (+ more) but I can't find the time to finally finish first working internal prototype

he means switching midi pins around, not on the uC
