Build / Debug

1. Clone the repo and cd into it.
2. git submodule update --init to pull Butano submodule.
3. cd into src this is where the actual GBA project is stored.
4. make -j$(nproc) to build using the makefile.
5. Open the output .gba file with your emulator to play.

Debugging:

• The .elf file contains all the debug symbols, run this to debug.
  • This is what is launched by VSCode debugging, specified in launch.json.
• If you want a better debugging experience you can play in the Makefile.
  • Set USERFLAGS to -Og to disable most optimisations.
