The batteries add up to 6v but in terms of tapping into power from the regulator is 5v. I've just scraped the traces on the front of the PCB for the select button. It shares a ground with the up on the d pad so I ended up using a diode to keep that working too. After some testing with LSDJ I do occasionally switch on the bluetooth by accident. I'll use a separate switch next time.

Isn't the gameboy 6V? And I was thinking, how have you wired the select button to the bluetooth button?

Thanks! It runs on a rechargeable 5v battery, so I just ripped that out and tapped a power supply from the 5v in the Gameboy.

Hi there! Really interesting project here, but, can I ask you about how is it powered? Thanks, and again, really sweet project

Alright thank you and for anyone interested here is the U.S. eBay link:

Thanks! This is the one I used: http://pages.ebay.com/link/?nav=item.vi … mp;alt=web

I would love a tutorial on this, this really is a awesome mod! Also could you post a link to the transmitter you used?

Thanks!

Nice work dude!

It's like the swiss army knife of modded gameboys.

He did every mod on that thing. It's a miracle the screws could keep it closed.

The point of pro sound is to make it sound better than through the headphone jack. This sounds better than through the headphone jack. I say GGbro.

OP, did you check out NeX's RGB boy with bluetooth prosound? He did the mod many years ago.

Catskull thanks for the link! I'd done lots of searching before trying this and not found any info before; interesting to see where he placed the module.

As for "prosound", I half-jokingly used that term as it quickly explains what the mod does. The module is wired up to the standard solder points for the prosound mod so that's why I used the term.

I never set out to find something suitable for gigging or recording, I just wanted to see if I could get it to work. You know, for fun. And it is a lot of fun. As for improving on stock circuitry, modern tech is becoming more and more wireless and it will be interesting to see what anyone else comes up with.

The point of prosound mods are to get better quality audio signals than available through the stock circuitry.  Transmitting your signal using a lossy data compression algorithm is going to give you a worse signal overall.

This IS nice work, I'm sure it sounds good enough for composing on or using around the house, but there's no reason anyone should use it in a live setting.

NeX actually did this a few years back. http://chipmusic.org/forums/topic/3205/ … pro-sound/

Overall though, I like yours much better. Can you link to the specific bluetooth module you used?
