Webapp that converts StepMania files in the SSC format to the SM format.

Does not handle any gimmicks like "Lifts", "Fake Arrows", etc.

But if there are chart-specific BPM changes and stops, this script is smart enough to split it into multiple SM files.

For example, given Aces for Aces.ssc, will generate Aces for Aces [Easy].sm, Aces for Aces [Medium].sm, Aces for Aces [Hard].sm and Aces for Aces [Challenge].sm

Usage Instruction

There's a running version of the webapp at https://nebupookins.github.io/ssc-to-sm/

When you go to that page, there'll be a blank textbox. Paste the contents of the SSC file there. For example, try pasting the following text into that textbox:

#VERSION:0.83;
#TITLE:ACE FOR ACES;
#ARTIST:TAG×U1;
#BANNER:ACE FOR ACES.png;
#BACKGROUND:ACE FOR ACES-bg.png;
#CDTITLE:./CDTitles/DDR A.png;
#MUSIC:ACE FOR ACES.ogg;
