Game Boy RW, stm32f4 side

This is the microcontroller side of my Game Boy reader/writer.

The code is written in C and uses the libopencm3 library to control the STM32F4. I have used a NUCLEO-F411RE, but other STM32 microcontroller should work too.

Supported commands are:

  • Reading ROM
  • Reading/Writing SRAM
  • Writing ROM on flash Chinese cartridges

Building

cd src
make gb-rw.stlink-flash

Debugging

openocd

arm-none-eabi-gdb gb-rw.elf
target extended-remote :3333
c
