This is highly experimental! Bugs may happen.

2. msbtEditor: https://github.com/IcySon55/3DLandMSBTeditor
3. nus3audio: https://github.com/jam1garner/nus3audio-rs

5. VGAudio: https://github.com/Thealexbarney/VGAudio
6. CrossArc: https://github.com/Ploaj/ArcCross

1. In the "Resources" folder, extract the msbt files in the /msbt using CrossArc
2. In the "Resources" folder, extract ui_bgm_db.prc and ui_gametitle_db.prc in /params
3. In the "Resources" folder, extract ui_bgm_db.prc and ui_gametitle_db.prc in /params
4. In the "Resources" folder, extract any nus3bank from Ultimate in /nus3bank and rename 'template.nus3bank'

1. Create a folder in /MusicMods. This folder can contains several audio files (only idsp tested so far) and a metadata file 'metadata_mod.json'. An example is provided.
2. The 'prefix' can be used to give an unique internal id to songs in case of multiple mods. Keep it short/lowercase (3 characters top). This parameter is optional. If you leave it blank, the id of the song will be used instead.
3. Keep all non localized fields lowercase.
4. Make sure the series_id value exists within the game (will provide enum later)!
5. Make sure the bgm playlist (playlist_id) starts with "bgm" or it will be skipped. If this is a new playlist, you must edit the stage db manually to reference it.
6. Make sure the fields values for "rarity" and "record_type" exist within the game (will provide enum later).
7. If you enable AudioCaching, the nus3audio files will only be generated once. Be aware that if you use a prefix the name of the files might keep changing and thus generating more files in the cache.
