No. Being an expert on the games doesn't mean you've seen the boot screens. Nobody knows much about the revisions until we find them. I had never heard anyone ever mention a World Warrior version from 1992 ever until we happened upon the board. Nobody knows all the revisions for all the Capcom 90s games as I've said a few times now. We just find them as we go. There are some websites out there that list some versions of them that are undumped but they aren't complete.
