a friend of mine wants to build his own arduinoboy. PM me if you're still doing this too!

uh and nex.. i knew you was selling in the past some arduinoboy diy kits.
Can i still buy one of they? PM me!

thanks for the replies!

can someone please test it? i should sync the gameboy to a drummachine using an arduinoboy.

I will have to find my underclocked DMG and give this a go, I always assumed it wouldn't work... Stupid me.

do it, its loads of fun, i had two gameboys synced and one was pitch bent, by changing the pictch just changes the key of the music without it going out of time.

the only problem is if you drop the CPU speed too much then it doesn't run fast enough to process the sync data properly, and then it starts to go out of time a bit

It should work fine generally, it'll synchronize to whatever source you give it at the same apparent speed. If you synchronize other devices to the game boy they will show a different tempo to the game boy but the timing should be correct. The game boy's internal clock shouldn't affect its ability to sync to external timing information.

Hi guys.

I'm just wondering if i could sync an half-clock-gameboy with another midi device.
There could be some problems with bpm changes/differences?
