There should be an ending where you do a genocide route then after you reload the save you wait on the main menu for 30 minutes then beat the genocide route all in one sitting then after you kill Sans you have a super duper ultra extremely hard fight against Onionsan. If you beat Onionsan then Chara says "Dang you got skills" then the game uninstalls itself.
