I recently beat this hack RTA and as far as I know, the only other person to beat it RTA is Metballs. I'd say it's somewhat of an elusive hack with only one video recording of one level and only a few posts about it in the Japanese Hack thread. It's a pretty difficult hack, nothing near the difficulty of Hyper 6 or S Mario though. I'm genuinely just curious about any other people that may have played it and what their thoughts on the hack were.
