RCA Output on a Super Game Boy

Always looking for an excuse to open something up

Always looking for an excuse to open something up

For my latest “chiptune” project, I’ve put in some RCA jacks on my Super Game Boy.

Of course the Super Nintendo already has the possibility of a component out (via RCA jacks), but, since the Super Game Boy basically contains all the circuitry of the Game Boy, this mod bypasses the Super Nintendo altogether.

If you’re interested in trying this yourself, check out this instructable for step-by-step instructions.

So… Does it sound better? I don’t really know, and I don’t really have the time to set up a comparison, but this mod sure makes it easier to get sound to my mixer.

Here are a couple quick recordings of games I had lying around:

The thing I have to be careful of, though, is that the clock speed of the Super Game Boy (4.295 MHz) is 2.4% faster than the Game Boy (4.194 MHz). A minor change, certainly, but a significant one if I’m trying to keep my music in tune between different devices, and I’m switching between the SNES and a Game Boy.

…like the time I brought my NOPera to Germany, forgetting that Europeans don’t tune to A440.
