GST and StepMania conversions

ddr-render.py mass converts xwb and ssq files to mp3 and ogg/.sm

Choose between scharfrichter (default), rhythmcodex, ddrcharttool, or none (GST only)

USAGE:

Arguments:
'-i', '--input', help='Input folder', default="contents/data"
'-o', '--output', help='Output folder', default="output"
'-c', '--sm-converter', help='StepMania tool', default=None, choices=["scharfrichter", "rhythmcodex", "ddrcharttool"]
'-s', '--series', help='Series to process (multiple ex: 19,20)', default='20'
'-t', '--threads', help='Maximum workers for thread pool', default=10

External dependencies for processing GST:

• ffmpeg.exe
• unxwb

External dependencies for also processing SM:

• sox
• in_place.py
• romkan
• scharfrichter/BemaniToSM.exe or rhythmcodex/RhythmCodex.Cli.exe or ddrcharttool.py

A mixture of tools are used:

• three sm converter options because each have their quirks
• unxwb because all other tools extract to normal uncompressed wav instead of the game's raw lossy ADPCM
• sox for converting to ogg because all other tools seem to add padding which introduces an offset requirement
• ffmpeg for mp3 tags
• series prior to A20 are untested, but imagemagick may be required for converting old .dds jackets where RhythmCodex and Pillow break

Merge music databases

merge-mdb.py merges two mdbs and makes a diff (with omni songs only for example)

USAGE:

1. Run arcutils_extract.py to get musicdb_omni.xml and musicdb_new.xml
2. Run merge-mdb.py

• Uncomment lines 82-85 to add " (OmniMIX)" to artist names in the merged output

3. Run arcutils_create.py to repack the output musicdb_merged.xml or musicdb_diff.xml (copy to data\gamedata\musicdb.xml first)

Import system573 songs to A20+ (old)

USAGE:

1. Extract packages folder from ddrextreme_omnimix.rar to here

2. Enable dotnet3

• (offline) mount windows iso ADMIN CMD: dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\sources\sxs /LimitAccess

3. Extract dxsdk_aug2007.exe\Utilities\bin\x86 folder with 7-zip(Open Inside) to here

• https://archive.org/details/dxsdk_aug2007

4. Extract magick.exe and ffmpeg.exe to here

• https://download.imagemagick.org/ImageMagick/download/binaries/ImageMagick-7.1.0-portable-Q16-x64.zip
• https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n5.0-latest-win64-gpl-5.0.zip

5. pip install lxml typing-extensions

6. Copy contents\data\arc\startup.arc and contents\data\arc\thumbnail\jacket_thumbnails_ja_8.arc to here

7. Run python3 573-to-a20.py

8. Copy the resulting contents\ over your original

Note:

• this is useless now
• artist name is set to OMNIMIX for all added songs because artists are not in the Extreme package.json
• background stage is set to 3 for all added songs
• the diff levels may not be accurate (old_diff * 1.5 rounded down)
• jacket aspect ratios are messed up
• most preview volume is deep fried (tried to match original preview levels)

Thanks:

• WF for extracted packages
• DM for original arc tool and lz77 (extract)
