Do you want to follow my route? So we can both have some "control" to this capture? If you are willing, go outside of Victory the door that leads to 1F1. Enter, take one step right, 3 up/north, you should hit that rock now, after which face west. Save your game.
You are now in a 4 step path. You will walk slowly (don't run) 4 step left to hit west wall, turn around by gently pressing right, walk 4 steps right to hit east wall, and then press left gently again to turn facing west and repeat the scenario
If you count touching each wall a "walk line" you will do 32 line walks (4 x 32 = 128) and you will turn/turnaround 31 times as when your 128 steps are over you will be at the same spot you starter touching that rock only facing east (when you began you saved facing west).
Also you said no keypresses but what is the date and time fo the seed?
