I tried /v/, since it was kind of videogame related, but not much response from them.
I'm in the process of trying to do mod a Gameboy Color, I'm starting off by adding a rechargeable battery, I will be using an Adafruit PowerBoost 500C USB Lipo Charger

I want to leave the case as untouched as possible on the outside, so I want to reuse the bottom AC port and just widen the hole to fit the micro USB from the Adafruit, I would like to desolder the port and try to somehow make it work with the Adafruit board, any one knows if this would even be possible?

that boosts the voltage to 5V, you don't need that
Gameboy Colors only need ~3V

why would it be impossible?
Just check with a multimeter set to continuity mode which pin is ground (touch the other probe to headphone ground or the negative battery contact, BT-) and then check which pin is +5V, here it's a little more tricky since you need to find the main voltage line. But my guess is that it is tied to the positive battery terminal so you can solder a thin wire to that big BT+ pad. As easy as that.
Also just use a TP4056 board to protect and charge the cell, this adafruit shit is too pricey.

My friend is helping me by drawing a schematic to bring down the voltage using resistors.

Thanks for the suggestion, but I actually already have the adafruit, came in today and I started messing with it, but I'll make sure to keep an eye out for the TP4056 for future projects.
