Hello, I got a PB on Piston Honda 2, but it was achieved on the Japanese version without Mike Tyson. So I'm wondering if it would still be allowed on this leaderboard. Thank you!!

We would not be able to accept it as a submission here unfortunately. For Gold Punch-Out, we've only set-up IL boards for the fights that are distinctly different from the fights in the final retail release of MTPO/PO. (Don Flamenco 1, Soda Popinski, Super Macho Man). As all other fights in the game are the same functionally as in the retail release, any IL attempts for those fights need to be submitted to the official MTPO/PO leaderboards. (For which the Gold Punch-Out cart is unfortunately not an accepted version of the game there).
