At most save points, the game is saved as soon as you click "Yes" on the save menu. However, when saving at the ship, you need to wait until after you clear the "Save Completed" text box before resetting.

Early Game

Run to the left after you regain control of Samus. Avoid arm pumping on any of the downward slopes here, since there's a decent chance you'll fall off of the slopes if you do. Fire a shot angled up when you're near the end of the low, flat section before the door. You'll also need to limit arm pumping after firing the shot, to avoid bonking the door.

100%

After coming from the Wrecked Ship, perform a shinespark diagonally right from near the ship. This will allow you to get to the ledge up by the Crateria Power Bomb Room. Lay a Power Bomb to open the door, and run through.

After you exit, do a wrap-around shot to open the door to Gauntlet Entrance, then shinespark horizontally left from the pillar below, through that door.

If you need to pause during the Gauntlet Spark in order to manually activate reserves, you will want to do it early in the spark. Pausing late in the spark could risk going Out of Bounds due to a Doorskip.

Any% Glitched

After X-Ray Climbing to get Out of Bounds, you will need to navigate to a certain point to activate X-Ray for the purpose of setting the Escape flag. This video shows the route typically taken for this category.
