In the 6

In the 6 is a category on the Extra Categories leaderboard, in where runners get stuck in the "6" in Bowser's Front Door. This run is most often performed with the Orb glitch in order to skip Iggy's Castle and Cutscene. Another method is to use ACE or Arbitrary Code Execution. A guide on In The 6 ACE is available under the Ace Guide section.

ACE Guide

ACE is Arbitrary Code Execution. The player writes specific bytes of data in the game by performing specific actions on specific frames or pixels in the game. The player then forces the game to read the arbitrarily written code, in where the game executes the arbitrarily written code.

Values

Here are the bytes that must be written to the game in order for the ACE to execute properly.

Byte Order

This is the order in which the bytes are written to SMW's memory addresses.

• 20 & E5 - Controller 2 Button Setup: L + Select + Y + B + Down + Right.
• 19 - YI1 Mushroom Drop
• C7 - YI1 2nd Mushroom Drop
• 1A - 1UP Shell Sprite Despawn Velocity
• FC - Shell Spit
• A9 - Shell Spit
• D0 - Shell Spit
• 92 - Shell Spit
• EE - Shell Spit
• 4C - Shell Spit
• 87 - Shell Spit
• 80 - Shell Turnaround
• 18 - Shell Kick Upwards
• EF - Shell Spit

In the photo, 76 can be ignored, and 04 corresponds to Yoshi's Position (Should be somewhere around the F6 value range).

Byte Explanation

Here is a little more in-depth explanation on how to achieve all of the values. Written in the order as seen in the photo.

• FC - The first shell in the level, shell spit on a specific pixel.
• A9 - After respawning all the Koopas (by running left), grab the last Koopa and shell spit on a specific pixel.
• D0 - After respawning all the Koopas (by running right), grab the first Koopa and shell spit on a specific pixel.
• 92 - After respawning all the Koopas (by running left), grab the last Koopa and shell spit on a specific pixel.
• EE - After respawning all the Koopas (by running right), grab the first Koopa and shell spit on a specific pixel.
• 4C - After respawning all the Koopas (by running left), grab the last Koopa and shell spit on a specific pixel.
• 87 - After respawning all the Koopas (by running right), grab the first Koopa and go under the platform; shell spit on a specific pixel.
• EF - Grab the shell with Yoshi and spit out the shell on a specific pixel.
• 04 - This value corresponds to Yoshi's X-Position. When performing the RLX Cloud setup, this value should be around F6.
• 76 - This value corresponds to a Sprite Slot's X-Position. However, we can ignore this value as it is of no use to the player.
• C7 - Collect the Fire Flower and then set up the screen with another screen scroll and drop the mushroom.
• 19 - You collect the first two mushrooms in the level and then drop the first one after setting up the screen with a screen scroll.
• 80 - Stomp on the first Koopa with Yoshi and dismount. Bounce off the final Koopa and kill the shell-less Koopa. Go right, then go left and perform the shell turnaround (quickly press right, then go left).
• 18 - Position the screen on a specific pixel, then kick the shell up. Then go to a spot off to the left and kick the shell up on a specific pixel.
• 1A - 1UP Shell Sprite Despawn Velocity. Setup by scrolling the screen and seeing when the top-right shell fragment despawns.
• 20 & E5 - This is the same byte that was used in the former 0 Exit strats. The button setup is: L + Select + Y + B + Down + Right.
• 14 - This value corresponds to the X-Position of the item in Yoshi's Mouth. It can be useful when setting up sprite slots.

Once all these values are setup, do the RLX item swap to achieve the Cloud and sucessfully execute the code. The pipe that leads to a sub-level will instead warp you to Bowser's Front Door

The description has some very important information as well: One important thing: Make sure not to lick any berries once you're in YI2 (running into them is ok). If you lick a berry, it overrides the values you set when you were in YI1.

PasteBin

There is also an In The 6 ACE Pastebin by MostlySMW:

Go to YI1, get a powerup in reserve and drop it so it sets $EF to 19, then get another powerup and drop it so it sets $EE to C7. Kill yourself and get back to YI2. Do everything normal, except make sure to kill the red shell after the message box and the 2 naked koopas. Do all the shells, up until the slot 7 one, where things get a little weird. You have to first kill the slot 9 koopa, do the turn around and the shell kick upwards, THEN spit it where it needs to be. You'll also have to use the fireball from that last koopa during the swap, since you killed the other red koopa. After you spit the shell, just continue and do the swap
