With only 1 tile of runway in the other room, Samus should ideally start on the last pixel of runway with X subpixels of $3FFF or less. Run toward the door, releasing forward for exactly 1 frame and pressing it again on the last possible frame before the transition. Starting with X subpixels of $7FFF can also work (e.g., by simply backing against the door ledge, then jumping and turning around mid-air); in this case, Samus must advance 1 or 2 pixels with an arm pump before the transition (e.g., firing a shot or pressing and/or releasing an angle button), and the shinecharge will be gained slightly further away from the door. After gaining the shinecharge, continue holding forward in order to make Samus stand. Then turnaround spin jump back toward the door, and continue spin jumping to reach the transition with a shinecharge. Alternatively, with greater difficulty but saving some shinecharge frames, after performing the turnaround spin jump, briefly moonwalk back, then retain momentum by boomeranging forward (switching from pressing backward to pressing forward on the next frame), and arm pump to reach the door quickly.

Ideal subpixels ($3FFF) can be achieved using one of several methods: 1) press forward against the door ledge (or a wall aligned with it); jump, and while mid-air, tap forward for exactly 1 frame to land with subpixels $BFFF, moonwalk back for exactly 1 frame to end with subpixels $3FFF. 2) press forward against the door ledge (from a platform below, assuming one exists) turn around (while on the ground), and moonwalk back two pixels, then jump and mid-air turnaround onto the ledge; if Samus jumped from the correct pixel but does not land on the ledge, then it was needed to moonwalk back 1 more frame; in this case it is possible to retry by doing a mid-air turnaround back onto the platform, and moonwalking back for 1 frame. 3) if X-Ray is available, press against the door ledge (from a platform below, assuming one exists) turn around (while on the ground), then jump and mid-air turnaround toward the door, and use X-Ray to turnaround in place away from the door; repeat this sequence 3 more times: jump, mid-air turnaround, X-Ray turnaround; then do one more jump and mid-air turnaround, high enough to land on the door ledge, and Samus should be in the correct position with subpixels $3FFF.
