Hacking and Flashing Game & Watch (Dual Boot)

In this video I'll be hacking Game & Watch (Mario Edition).

I'll be wiring debug port to USB-C port, upgrading flash chip and flashing retro-go and emulators along with original firmware (ie. dual boot).

Wiring debug port to USB-C allows for easier flashing in the future (no need to disassembly the device) and dual boot allows for original firmware to exist alongside retro-go emulators.

2. Patching original firmware

export OPENOCD="/opt/openocd-git/bin/openocd"
make PATCH_PARAMS="--device=mario" LARGE_FLASH=1 flash_patched

3. Building and flashing retro-go

export COVERFLOW=1
make EXTFLASH_SIZE_MB=63 EXTFLASH_OFFSET=1048576 INTFLASH_BANK=2 flash
