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 69 A presses, a theoretical 70 star run would take 2 A presses (1 in BitFS and 1 in BitS), and 52 stars are possible without pressing A. Out of the 69 A presses left in the 120 star run, 48 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
#2 1 JRB To collect the chest star
#3 1 JRB To ground pound the blue coin switch
#4 2 BBH To get to the third floor
#5 1 HMC To jump from the pole for reds
#6 1 HMC To get to the Toxic Maze star
#7 2 HMC To jump dive from dorrie's back
#8 1 HMC To ground pound the blue coin switch
#9 1 LLL To collect the elevator star
#10 1 SSL To get onto the entrance to the eyerok battle
#11 2 SSL To get out of the pyramid elevator
#12 1 DDD To jump off of a cloned pole
#13 1 DDD To jump off the back pole for 2 red coins
#14 1 SL To shoot from the cannon
#15 1 THI To double jump to a higher platform and collect red coins
#16 1 THI To dive to the upper platform and grab the high red coin
#17 1 TTC To jump up the cogs for bob-omb glide
#18 3 TTC To double jump off the lower hand
#19 3 TTC To wall kick to a higher platform
#20 3 TTC To get off the elevator by the pole
#21 1 TTC To jump past the moving bars
#22 1 TTC To wall kick to the moving bars star
#23 1 TTC To get on to the first rotating block
#24 1 TTC To double jump off the second rotating block

#40 1 BitS To grab the red coin on the sloped platform
#41 1 BitS To get past the pole (reds only)
#42 1 BitS To get past the pole with the red coin (reds only)
#43 1 BitS To jump from the last red coin's platform
#44 6 Castle To enter THI
#45 6 Castle To enter TTC
#46 1 Castle To go to RR
#47 1 Castle To enter SA
#48 1 Castle To go to WMotR

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

Possible A Press Saves

Jolly Roger Bay

It may be possible to get speed from the pillar and reactivate it some other place to ground pound the blue coin switch 0x for 100 coins, and would save A press #3. Ivan178 has shown that it is possible to get speed from the pillar to get Blast to the Stone Pillar 0x.[4]

Shifting Sand Land

A while after Zyon showed a potential A press save in Whomp's Fortress, Ivan posted another clip[5] of him killing a goomba[6], then bouncing on another goomba and collecting the other goomba's coin with good RNG, spawning a 100 coin star that allowed him to get past the pole with a precise Star Dance Clip, and would save A press #10.

Dire Dire Docks

Ivan178 posted two videos of him getting 3 of the glitchy ledge grabs to get up the corkboxes up the ship all first try, and another video of him diving onto the nearby pole allowing him to get up to the red coin platform 0x.[7] This showed potential for Through the Jet Stream 0x, and Collect the Caps 0x.

Rainbow Ride

On February 10th 2023, PapaQBall shared an idea to save the 32nd A press, to get over the first blue block in Rainbow Ride 0x using VSC from a slidekick bounce from one carpet to another carpet, then ledgegrab up on top of the blue block.[8] Unfortunately, the ledgegrab was too slow. However, pannenkoek2012 showed later that it would be possible to get back onto the carpet with a dive rollout on the edge of the block.[9] This would save A press #31

Bowser in the Sky

Currently, the A press count for Bowser in the Sky and BitS reds is 1 and 6 respectively. All of the improvements made in the Bowser in the Sky 1x video can be replicated in 6x to get BitS reds down to 2.[10] The Chuckya Wrong Throw setup is also repeatable, meaning you can do it however many times you want. This leaves the final count for BitS to likely be 1 for both reds and no reds.
