I've built a few arduinoboys and am wondering anyone's experience on running the arduino off the game boy 5V link port pin. I've built the arduinoboy strictly for MGB mode so I'm not concerned with sync, just a consistent flow of midi data with no dropouts or glitches.
According the arduino spec you are supposed to supply the VIN on the board with 7v-12v but the gb only gives around 5v. Some folks on various forums have said running it at 5v can cause problems with the circuit. I have never tried running it off a 9v battery - could this be the problem I've been having?
I'm pretty sure it's not my soldering skills or an issue with following the schematic as I've made around 8 of these. Some in a dmg and others in external cases. It happens on the dmg-01 and the color game boy. It's also not constant and never that bad but it is noticeable to me when it misses a note, hangs, or plays the wrong note.
