So here is what I have so far. I just started.
I yanked out the GB slot and removed the pointer holder inside the DS.
Next I am fitting a second battery that will be flush as you can see in the pic.
The pic shows one of my broken clear case bottoms that now hold the battery, perfect for illustration purposes.
Now I will attempt to solder wires to the 2nd battery EDIT: (no switch, batteries are now wired in parallel also added 2 bright LEDs and switch to use it as a flashlight at night.)and run it to a switch so I can charge each one at a time.
I am not done because I want people to look at it and see if an ideas pop up.
The mobo still works. It's not all put back together. I need a new case before I can finish it.
enjoy.
PS: You will need to forget about GBA carts.
