The goal game platform can be activated with A or B, and can be mashed. The earliest frame you can activate the goal game is:

This frame gives you the fastest possible goal game. The frames after that one are 10, 46 (ledge grab on "6"), 4, 19, 30, 66 (ledge grab on "5"), etc. frames slower. Not pressing anything is 64 frames slower.
