To get them ready for openbor,
- open character in Fighter Factory.
- delete portraits and any effects and other uneccessary sprites (you should rip them separately)
- double click the first entry in the main palette used for the char sprites (the transparency index)
- change 'Alpha Channel' from 0 to 255 (this will make it visible)
- Click in the menu 'Sprites' and choose ' Save Image (aligned)...
- Choose 'ALL'
- save to desired directory.
- Click YES to save axis information to file. (axis.txt)
Now you will have perfect aligned sprites ready for OpenBOR. You can run the images through PalApply if needed.
axis.txt
If you want to make spritesheets then there's a few programs that will do that. Just search 'spritesheet packer'
I just use this online one, but I only use it to pack sprites for making palettes.
