[REPUBLISH] Koishi’s Extractor BlackCat.4.1


NOTE TO DFOG ONLY: If you encounter the password prompt when opening NPK files, just use old version of Koishi or use ES to open instead. We have various backups in github and mega.

Too lazy to translate the release notes!

The dressing room function is revamped. And if you want to see the thumbnails or icons you must localize the dressing room. Click the last icon on the toolbar (the symbol of the earth) and select Localize Current Class.

The original author is a Touhou fan so I tried to preserve the Touhou style translation. :stuck_out_tongue:

This software is called “Koishi’s Extractor”, and the version is called “BlackCat.4.1”. The author of the software is “断幺九の猫耳恋”.

(JS Delivr does not support .exe files download so JS Delivr stream split is not available! )


Previous Versions:


There’s no installer, so just run the EXE and the tool will start up and allow you to view and edit NPKs and IMGs. But, it’s in Chinese, of course. Most texts have been translated into English.
