I did some stuff different:
- Placed the battery inside the game cardrigde (may even make it swappable)
- Used an Arduino instead of a Teensy for button input to keyboard commands conversion
- Used a different charger board that fits nicely behind the power port in the GameBoy case
I may even upgrade the battery or make in swappable in the future as I have
more space but for now it is fine.
