The RTABC (Real Time A Button Challenge) is a variation on the popular A Button Challenge, where all gameplay must be done in real-time.

Completed Runs

The current RTABC 70 Star world record, achieved by PurpleJuiceBox, finishes with a total of 22 A Presses and with a time of approximately 4 hours, 32 minutes, and 52 seconds.[1] The current RTABC 120 Star world record, achieved by BillyWAR1, finishes with a total of 216 A presses and with a time of 8 hours, 36 minutes, and 6 seconds.[2] The current RTABC "Max Stars 0xA" world record, achieved by Zyon, finishes with a total of 37 stars and with a time of 4 hours, 41 minutes, and 36 seconds.[3]

The RTABC spreadsheet contains leaderboards for individual stars, stages and full game categories; optimal routes for 70 Star, 120 Star, and Max Stars 0xA; conjectured improvements, and many other useful references.

A Presses Left

A unique A press refers to a single circumstance under which the A button must be pressed during a run. This circumstance may occur multiple times, leading to multiple A presses; if a workaround is found for the unique A press, all of those individual A presses may be saved.

Currently, a theoretical 120 star run would take 75 A presses, a theoretical 70 star run would take 6 A presses (1 in BitFS, 1 to go to BitS, and 4 in BitS), and 48 stars are possible without pressing A. Out of the 75 a presses left in the 120 star run, 52 of them (give or take) are unique. Below is a table listing all of them:

A Press # Multiplicity Stage Purpose
#1 1 BoB To shoot from the cannon

Some A presses require A to be held, but not pressed. These A presses are called Half A Presses and can come from a previous A press instead of a new one, so saving one wouldn't actually lower the A press count.

The half a presses are listed below:

Half A Press # Multiplicity Stage Purpose
#1 1 DDD To outswim the whirlpool
#2 4 DDD To swim with a shell for cloning
#3 1 WDW To swim faster and catch the elevator
#4 1 BitS To speed kick across the starting platforms
