Hiya folks,

This is a project I've been working on for quite some time.

It's a remade audio filter board for the DMG. It consists of an additional PCB mounted jack. All components remain in tact, and are replaced with new ones. (New caps, new inductors)

First of all, I'd like to say that yes, I know this project may seem useless to a lot of people. It's not at all useless to me, and may not be useless to other modders. So there's no need to point that out.

This is not a practical replacement for a panel mount pro sound jack, both because these are expensive to make and a little more difficult to install

The benefit to this mod is a lot of important space is saved in the DMG. The installation, if done correctly, looks professional. This is likely how it would have been if Nintendo decided to include a line out jack.

I spent a lot of timing trying to find the 'perfect' components for this. Lots of datasheet reading. I didn't want to use cheap jacks, and a lot of the PCB mount jacks I purchased and tried were very cheap and easily breakable. This one is perfect because from the outside, it's a very similar size to the stock headphone jack, but green- which usually signifies a line out jack.

Another plus is the durability. You don't have to worry about the nut coming unscrewed for the jack, and no glue is necessary to keep it in place.

It also adds no height to the DMG. I know this sounds petty, but it won't interfere with things like nuby speakers and such.

If anyone would be interested in purchasing one of these, please let me know so I can take into consideration how many need to be ordered. Due to the cost of materials, this will probably run around $25 give or take.

And onto the pictures:

Why, yes! It does say 'pro sound' instead of 'line out'. Why? Almost the entire chiptune community knows of this mod as the 'pro sound mod'. The term is  exclusive to gameboy mods (for the most part). Despite it maybe being a bit random, and perhaps rather silly sounding and not an official term, I like it...

The inductors are currently just branched with component legs as they haven't arrived yet. Messy soldering, but it's just a test.
