Your headphone jack looks more like a switched mono jack. Maybe I'm wrong.
hahaha are you talking about mine? I didn't even realize I was the one that started this thread two years ago. Needless to say, my SGB prosound is working fine.
I wonder if there is more about the arduino that needs attention. As I mentioned in my first post, the newest IDE finds multiple errors and they are all where it names the samples out as "not declared in this scope". Then I went back and tried reprogramming it with version 1 of the IDE and it seemed to work ok-- since it didn't have errors. Earlier today I tried reprogramming the arduino again in version 1, and i noticed it had 2 usb ports, tried the second one this time and it immediately crashed my computer in a way I've never seen-- black screen and some strange mac warning screen. Anyway, since i'm also a newby at the arduino, it is as simple as opening the sketch and hitting send right? Is there any way to verify the contents of the flash memory on the arduino?
Funny, I've run into similar crashes when programming an arduino from my mac. The screen you saw was a kernel panic right?
By two usb ports, do you mean two serial ports showed up? TTY.usbport and CU.usbport? You should use TTY always though. This page offers more info: https://www.arduino.cc/en/Guide/MacOSX
AFAIK, the arduino IDE will verify itself when you program it.
How are you sending midi data to the arduino?
What model of arduino are you using? Can you post a picture of all of your hardware?
I can say, I've had a rough time getting midi data out of an arduino with my midi gear. I've tried several models and I get absolutely nothing on my FB-01 and a cheap usb midi cable. I also connected it to an analyzer and verified that data was coming out of the arduino's tx line, but I still got nothing on my synth. So really I need as much help as you do hahaha. Like you, I'm at my wit's end. I don't have a master system to try, but I do have a game gear. I'll see if I can get the hardware together to give it a shot.
Forum rules state you have to set a price for it btw!
Check again, he is.

You would need something to do what the arduinoboy does, ie convert midi serial data into the serial data the gameboy is looking for.
Does anybody have a good document the explains the Gameboy's serial? Is it just UART?
Can I at least buy one of the min64's off you and use it?
So you want a teensy and an arduino in there? Or are you going to attempt to put them on the same board somehow?
Just listened to the whole thing. Really great stuff! Reminded me if the Chrono Trigger OST, probably because that has many of the same themes. I wish an NES game had this soundtrack! Favorite track was the wild west one.

That's rather tempting but I can't justify having two consoles. I game, not compose you see...
You could buy both and sell one to me? Split it 30/20 for the 2001/1001 respectively?
looks neat, but if it's just emulated sound why not use a VST or something? you'd have more control that way and would save $80.
It may be a poor argument, but a computer plus ableton or whatever is much more than $80. At the same time, I can see what you're saying. But couldn't you make that same argument for pretty much any synth?
So I built another one using a breadboard and an Arduino Max 2560 and I get the same results - nothing. I'm wondering if My midi gear isn't cut out for an arduinoboy? Has anyone successfully used a rockband keytar with an arduinoboy?
At this point I'd even be willing to ship it to someone who has known good midi gear to test for me.
That actually looks super cool!
I wouldn't be surprised if this was just painted over the "gold gameboy" from yesteryear.
I'm fairly certain that Josh-Schmosh AKA PianoGameboy made this.
The pro micro is the 5v version.
Pin 7 is the base of the second transistor in the opto. I don't understand fully, but it makes the rise/fall time of the opto smaller. Adding the resistor there is suggested by Nitro2k01. http://blog.gg8.se/wordpress/2009/07/26 … -glitches/
I'm using an Arduino Pro Micro. I did have to modify the code a bit because the pro micro doesn't have I/O's 11, 12, and 13 but instead it has 16, 14, 15 where they should be (compared to a pro mini). I'm sure that those led's are working though, because the startup sequence works correctly and I can cycle through the led's with no problem.
Did the opto circuit look okay to you?
Thanks a ton for your help btw. I really appreciate it!
Thinking about this a little bit more, I suspect the 6n138 is having problems (among other things). Again, it doesn't make sense to me that midi out doesn't work either, but maybe there's more than one issue at play.
If I understand correctly, I should NOT be able to program the arduino when it's in any mode other than programmer (with all leds on). However, I am able to program it regardless of which mode I'm in. If I understand the code and schematic correctly, the 6n138 vcc is tied to arduino I/O pin 4 so we can control the power on the fly. I suspect that the opto is not getting power correctly. I will attempt to connect 6n138's vcc directly to the arduino's vcc and see if I get any better results from that.
Other than that, I am at a bit of a loss here. Help me Jazzmarazz, you're my only hope!
