GNWManager is THE game-and-watch device manager. GNWManager is responsible for getting firmware onto your device, managing the filesystem, and other device administrative tasks.

Features

Standalone and simple to install.
- No more installing many different tools with various patches!
Fast internal and external flash firmware flashing.
- Hardware-accelerated hashing for rapid duplicate discovery.
  - Only syncs changed data.
  - Minimizes flash erases and writes, extending flash lifespan.
- Double buffered, asynchronous, LZMA-compressed transfers for maximum speed.
Complete filesystem management.
- Backup and restore files.
- Interactive filesystem explorer.
Automatic Real-Time-Clock (RTC) configuration.
Developer tools:
- Easily monitor device printf statements and launch GDB sessions.
- Capture screenshots, regardless of the running firmware.

Installation

It is highly recommended to use pipx to install GnWManager. Currently, GNWManager is not available on PyPI (but the name is reserved) until upstream PRs are merged. Until then, the best way to install GNWManager is:

git clone https://github.com/BrianPugh/gnwmanager.git
cd gnwmanager
pipx install .

That's it!
