WriteBoy

WriteBoy is an Arduino based ROM image writer for GB Memory Cartridge.

Requirement

Software

• Arduino IDE
• Python 3.x and pyserial

Hardware

• Arduino Mega 2560 R3
• GB Memory Cartridge (DMG-MMSA-JPN)

Interface

Usage

Writing to GBMC

Assume that Arduino is connected to COM3.

1. Prepare a ROM image (.gb) and MAP file (.map) - using GB Memory Binary Maker would be nice
2. Write a MAP to GBMC by followng command: python writeboy.py --port COM3 --write-gbmc-mapping filename.map
3. Write a ROM image to GBMC by followng command: python writeboy.py --port COM3 --write-gbmc-rom filename.gb

Other features

• SRAM Read/write
• ROM dump

See python writeboy.py --help.
