You can load the ROM onto a flash cart or in an emulator. The key mapping is as follows:
- D-Pad to choose a character from the map
- A selects the current character
- B deletes the last character
- SELECT sets the color scheme (black on white or white on black) and rotation
- START prints the current string
If your printer is properly connected, the printer icon will show a checkmark symbol.
The ROM can be compiled with GBDK 2020. The repository contains a Makefile for Linux and Windows with WSL that will work if you clone it in the gbdk folder. For convenience, a compiled ROM is provided in the releases.
