This is another variant of Karate Blazers, labeled "World?". The question mark indicates uncertainty about the precise regional targeting or release version. This ambiguity makes it harder to definitively determine which geographic region it was initially released in or the exact differences from other known releases of the same game.   More specific details would be needed to provide a comprehensive account of this release.
