GBCam Companion

Bring your GameBoy Camera into the modern age! GBCam Companion turns your Android phone into a live preview screen, gallery, and print station for the RP2040-based GameBoy Camera Adapter. Connect the adapter over USB-Serial (OTG), snap photos on your classic GameBoy Camera, and watch them appear instantly on your device — then apply retro palettes and print them back to a real GameBoy Printer.
Whether you're a retro-gaming collector, a pixel-art lover, or just chasing that unmistakable 2-bit aesthetic, GBCam Companion gives you everything you need in one lightweight, privacy-friendly app.
