Prototype save converter for MH3U. Converts 3DS save file into Wii U format and vice versa.
This is very much a quick and dirty implementation and you should expect some data to not get converted properly. Always back up your save files in case things go wrong.
Requires Python to be installed on your computer.
Converting a 3DS save file into Wii U format:
python convert_to_wiiu.py path_to_3ds_user1 output_wii_u_user1
Converting a Wii U save file into 3DS format:
python convert_to_3ds.py path_to_wii_u_user1 output_3ds_user1
There's also a Qt GUI version available:
python app.py
