Anyhoo, what needs to first be done is that you need to gain a basic understanding of programming if you want to make any of these work. Looking at the Kirby file (using Notepad++, but I'm sure you can open it up in regular ol' Notepad), it first finds the URL of the sheet in question (in this case,
http://spriters-resource.com/nes/kirbyadv/sheet/2581 << this guy), and then it cuts out holes of a specific W times H size starting at the position (cropX, cropY).
It also sets the background color transparent in this same call, so don't forget it.
The program normally reads your first crop call as the idle sprite. For future animations, you need to specify each X and Y position your frame lies on the sheet.
I'll assume you're doing this from a sheet on your computer. Just get the filepath inserted where the URL currently is, then give the exact file name in the "uri" string.
It sounds like a lot of work, but when you get the hang of it, it's actually a really simple program~
