Performing Crackslide can be broken down into modular sections, where you can choose different options based on your preferences and it won't affect the later parts too much.


Performing Crackslide can be broken down into three quite modular sections, where you can choose different options based on your preferences and it won't affect the later parts too much.
The easiest combination of strategies are:

| Setting Mario's z-position ||  [[RTA_Guide/Crackslide#Easier|Double ledge grab right pillar (easier)]]

In order to get enough speed during the C^ slide, we need to set Mario's z-position quite precisely. It should be between 1560 and 1563 (non-inclusive) to do the B-press exit strategy, and between 1560 and 1560.9 to do the B-pressless strategy. The B-pressless strategy requires a more precise z-position, but overall it is still easier and thus recommended for beginners.

During practice, we can use the [https://sites.google.com/view/supermario64/usamunepj/usamunerom Usamune Practice ROM] to see Mario's z-position. Navigate to HUD -> MEMORY -> SLOT5 -> press A -> Change X to O.

From the door, jump and switch to Mario cam, press C-Right just before ledge grabbing the pillar, and aim to grab the pillar closer to its right edge. After a quick get-up, jump and ''gently'' press right so Mario ledge grabs the right side of the pillar. Let the camera snap behind Mario, then get up.
On entering the basement, single jump, switch to up-right, and press R. Press C-Right just before ledge grabbing the pillar, and aim to grab the pillar closer to its right edge.
The gentle right input ensures that Mario's z-position is close to 1560, which guarantees that the B-pressless exit method will work.

We can also line up Mario's z-position with a texture on the pillar. Aim to have Mario's pant leg just barely touching the white line.
Mario's z-position can also be lined up with a texture on the pillar. Aim to have Mario's pant leg just barely touching the white line. This should only be used as a backup after failing one of the above setups.

Get up from the ledge grab, backflip, then punch twice. Then ''tap'' Z (not hold), press up on the stick, then press A to backflip. Tapping Z allows you to buffer the up input.

Alternatively, you can press R, then C-Down, then C-Left and hold up-right. This means you don't need to switch from right to up-left while in the air. However, this requires a marginally more precise z-position (high 1560.9xx won't work), and can be notch dependant. Try to make sure not to be holding more towards right than up.

If you are doing the double jump setup, count 12.5 beats, or just over 3 bars, from when you get up from the second ledge grab.

After you arrive at the door and interact with it, scroll through the text, Continue holding A after the final text box, hold the stick away from the door (usually down-down-right), then press B as soon as Mario is able to move to buffer kick through the door.
