The original Gameboy Advance had the best form-factor of that generation. Unfortunately the following AGS-101 had the better backlit screen. How about combining the best of both worlds to build the ultimate AGB-101 ? You can also use an AGS-001 screen to have it frontlit.
Here's what you get:
- 1x 32 or 40 pin ribbon cable to connect an AGS-001 or AGS-101 screen to AGB-001 board.
- Pre-soldered wire
- Ribbon with brightness switch
Refer to this guide to know exactly which model to get for your use-case.
