This one will do. It has a chicken.

This could still be improved by doing a more TAS-like mash inside the hit boxes of the early bosses, or by learning the White Dragon's movement pattern properly, but I'm done with it for now.

This run uses the "Horoporo" (ほろぽろ) code to replace the protagonist's sprite with a chicken. This is a cosmetic effect only and has no effect on gameplay.

Played on a SGB2 on SNES hardware and recorded with a RetroTink 5X-Pro. Final time determined by counting frames in Avidemux.
