Retimed it myself and got a time of 18:22.717 using https://retime.mcbe.wtf/. The start frame was when the character appeared, end frame was when Congratulations appeared. Start Frame: 998, End Frame: 67162, FPS: 60, Total Time: 18:22.717.

Played on the Retroarch Nestopia 1.52.1 b99ede3 emulator.

*modedit - changed time to 18:01 to be consistent. SRC rules have been updated.
