AAAAAANNNNNDDD I'm back with another tutorial folks!
The tutorial I seen for ripping sprites from Cuphead uses Unity Assets Bundle Extractor. (Which I linked here)
But it's kind a difficult way, because you export them from a 'Texture2D' file (which is easy), but then you have to organize them (which is an extreme pain in the butt to do, and why the Cuphead Section on tSR lacks a lot sprites from it)
This tutorial shows you how to rip them easier than what the other tutorial shows you how to rip them.
1. First up, you'll need to download AssetStudio.
2. Open up Cuphead's files. (I recommend opening the 'folder' than one file. You'll get everything if you open the folder.)
3. Click on 'Asset list'
4. Click on 'Filter Type', then click on 'Sprite'. (I highly recommend that you sort the sprites by name '0-Z')
5. Find the sprite you're looking for. It varies on what you're looking for. In Cuphead, some things are named kind of differently than others. Like, some of Mugman's sprites have 'mm' in the file name.
6. Select the sprite (or hold SHIFT and select multiple sprites that you want), click on 'Export', tell it to export 'Selected assets' (or whichever one you prefer), and choose the file you want to export them in. (The files you export will get dumped into a folder named for what type of file it is. In this case, since you're exporting a sprite, the exported folder will automatically be named 'Sprite')
Aaaaaannnnnddd that's all! I hope this was helpful! If you see anything I missed, be sure to comment down below and let me know.
Good luck ripping Cuphead's sprites!
