This is a modified fork of the orginal repo which adds dance double support instead of dance single charts.

Roughly convert Friday Night Funkin .json charts to doubles simfiles for StepMania
Or convert StepMania simfiles to FNF charts.
Very WIP but it works, kinda.

Usage: Drag-and-drop the FNF .json chart or a StepMania .sm simfile onto fnf-to-sm.exe
Or use the command line: python fnf-to-sm.py [chart_file]

For FNF-to-SM, if you input the Normal difficulty .json, and have the
easy & hard .jsons in the same folder, then FNF-to-SM will output
a single .sm with all 3 difficulties.

SM-to-FNF currently only supports Challenge Single difficulty.
The output "blammed.json" is meant to replace "Blammed", Normal difficulty.
