Regarding missing sprites from SRW Z3, a Tutorial
Some of you may or not know but I didn't personally extract Z3's sprites, so I don't really know why there are missing sprites on the batch. I do know a method to view them and save them but is very time consuming so I'm not doing it anytime soon. If you are in a hurry to get these sprites you can try this.
You need 2 programs: CriToolPack and TextureFinder2.0. You obviously need your copy of the game too.
Find the folder showed in the image.
Open the file with CriToolsPack. The one that has the missing cut-ins is PCI.cpk
Choose a file and extract it.
Open it with TextureFinder2.0
Activate Pixel Flipping. Pixel format is 8888. Search for the correct colors with the arrows in Shift.
The width of the sprites is variable so it can be anything from 256, to 2048, and many other numbers in between. It varies from case to case. You'll have to search the correct width for each section of the file if the file has more than 1 section. If the file has more than one section it will be below the current set of sprites.
Save the file with the camera button. It will be a bmp (no transparent BG, sorry!).
If any of you know how to extract them with transparent BG please let me know in the comments.
