A CLI and library for introspecing, extracting and decoding wii Nintendoware sound files.

mrst list|extract|decode [options] file

-o/--out output file path for extract and decode operations. If not provided, a sensible name will be chosen (if one file is output, the same as the input with different file extension, otherwise a directory with the same name with ".d" appended to it)

Prints various information about the file

Extracts files from archive (BRSAR or BRWAR)

• --decode additionally decodes subfiles while extracting
• --extract-rwar For BRSAR extraction, automatically extract any BRWARs encountered

Decodes file into modern standard format. BRSTM/BRWAV files are converted to WAVE, BRBNK (and corresponding RWAR if applicable) files are converted to SoundFont 2 (sf2) and BRSEQ files are converted to MIDI.

Although I tried to incorporate all the features of past decoder implementations, MIDI conversion is a work in progress and not all RSEQ behavior can be translated into MIDI.

Eventually it would be nice if this tool supported re-converting from common formats to nintendoware (mrst encode) and re-packing archives (mrst archive).
