You know, I think it would be pretty easy for a skilled pixel artist to restore those for a further use in a fan games or a mods.
I also think that every animation in SF II that lacks some frames should be updated.
And also I think it's pretty disappointing when the game meets some kind of limitations due to whose some content needs to be cut out.
I can try to restore Kazin's idle and palette, if you want. I need to do some pixel art work to back into the groove anyway
Not sure about the staff though, but I can try it too.
