Sonik Sprite does not reccognise the ROM ID ". The ROM you selected may be corrupt or their is currently no support. Maybe someone give me s1built.bin?
Sonik Sprite is outdated and you should not use it. It will not work with a dissasembly. You're better off using SonMapEd or Flex to edit character art.
I actually edit sprites in Sonik Sprite by this trick: 1. Edit. 2. Save & Close. 3. Splitting the edited ROM. 4. Copying & pasting into my true disasm. Somehow, this method works, and it's very handy. That's pity, about when I will need larger sprites, I need to deal with mapping editors anyway.
