Need help ripping Touhou 10.5 sound effects

[Nevorist]

There is a tool called Brightmoon for what you need that can be downloaded here. Simply click on th4_4486.zip to download it and open the th105.dat files with it (you can only have one open at a time), select all file with Ctrl+A and extract them where you want. Just be sure to let the extraction window close itself rather than pressing cancel thinking it was finished like i did at first.
If you ever want to extract other Touhou related stuff i highly recommend that page.

Hope it helps
