I was happy to learn my notes for each hole translated almost perfectly from the SNES version to this one on Mega Drive which allowed me to get a decent run pretty quickly. I think I can easily get a sub-21 with a few more attempts.

Played on BizHawk 2.6.2

(Note to mod: I think we need Genesis added as a Platform choice. It only lets me pick SNES.)
