Audio Mods: How To

1. Download both unxwb (Link TBU, program created by Luigi Auriemma), and XWBTool (Link TBU, found on Microsoft's GitHub) and extract both of them to your working directory.
2. Copy over the .obb from your phone's internal storage to your working directory. The OBB can be found at Internal Storage/Android/obb/main.2.com.chucklefish.stardewvalley.obb
3. To unpack simply run unxwb main.2.com.chucklefish.stardewvalley.obb in Command Prompt which should output 87 files named 00000000.wav etc... It is highly recommended for cleanliness to move the unpacked .wav files to a separate folder.
4. Replace any of the files with audio of your choosing, however you MUST keep the file names the same.
5. To repack, simply run XWBTool "wherever you extracted and moved the .wavs to/*.wav" -o Music.xwb (The output file must be called Music.xwb when repacking). Then rename Music.xwb to main.2.com.chucklefish.stardewvalley.obb.
6. Move the now modified .obb back to Internal Storage/Android/obb/main.2.com.chucklefish.stardewvalley.obb.
7. Enjoy your modified music!
