my video uses RTA timing instead of SDA/gain control.

main improvements:

1. pause/unpause when each stage begins to make the screen scroll down immediately instead of a small wait (incl stage 1 but that doesn't matter in SDA timing)
2. new points route in phase 4 with golden hammer. this makes it so the super bonus will jump the score to over 26000 instantly instead of waiting for the point countdown to fill it.
