Version 1.0.1

Version 1.0.1 is a version of the game that was released as a day-one patch, meaning it was available from the moment Super Mario Odyssey released digitally. The patch included a number of tweaks implemented as preventative measures to prevent certain types of exploits, such as removing certain sequence-breaking behavior. Because it was a day-one patch and the community had not found any glitches yet, the version 1.0.1 patch primarily contains fixes aimed at preemptively preventing unintended behavior, rather than patches to specific glitches or exploits.

Version 1.0.1 and its successor, version 1.1.0, are often collectively referred to as "version 1.1", since the only difference between them is Korean language support, although this terminology can often be slightly misleading.

Because there are no cartridges with a base version of 1.0.1, it is no longer possible to obtain a new copy of this version without custom firmware. However, cartridges can be found with a base version of the nearly identical version 1.1.0.

Changes

The following is a list of changes compared to the previous version, version 1.0.0:

• The collision properties of the invisible wall in the Cascade Kingdom that is bypassed during First Moon Skip were altered, meaning the methods of bypassing it are different on versions 1.0.1 and later when compared to version 1.0.0.
• It is now possible to clip through the ground in the Cascade Kingdom near where the bridge lands after collecting Our First Power Moon, by ground pounding a certain spot before the bridge has fallen.
• The Madame Broode fight in the Cascade Kingdom can no longer be triggered before collecting Our First Power Moon, making First Moon Skip no longer useful as a sequence break.
• If any Story Moons were skipped in the Cascade Kingdom using either First Moon Skip or Madame Broode Skip, they will now automatically be awarded to the player upon returning to the kingdom or completing the game, even if they were skipped before the game was updated to version 1.0.1.
• Falling off of the Warp Painting platform in the Luncheon Kingdom before reaching the kingdom normally using the Odyssey will cause the game to attempt to place Mario inside a bubble. This attempts to prevent Bruncheon, but if the bubble's safe spot is never set (which can be achieved by only standing on top of the painting, since the safe spot cannot be placed there), Mario cannot be placed in a bubble, allowing the kingdom to still be accessed early.
• Warp Paintings will now only be enabled if the story in the kingdom on the other side is progressed to the point where the opposing painting opens. This eliminates some behavior where painting portals can be entered only in one direction.
• The Warp Painting, Checkpoint Flag and Power Moon on the faraway island in the Metro Kingdom now exist in the nighttime scenario, while they previously did not. This fixes some strange behavior that would occur when entering the painting from the Sand Kingdom before defeating Mechawiggler, in which Mario would spawn near the Odyssey instead of emerging from the painting on the island.
• Three loading zones that were erroneously active in the Snow Kingdom before completing the Bound Bowl, but that cannot be accessed early without clipping out of bounds, are now disabled.
• A bug is fixed where Talkatoo in the Snow Kingdom was able to suggest moons that were only available after completing the Bound Bowl, before the Bound Bowl had actually been completed.
• The metal crate containing a Moon Shard in the Second Courtyard of Bowser's Kingdom will no longer yield a coin if it is poked 200 times while inside a Pokio capture. It will still yield a coin if broken normally with a bomb. Because of this, version 1.0.1 or later is required to complete the game without collecting any coins.
• Uproot hitboxes now only become active after the Uproot has fully emerged from the ground, rather than as soon as it spawns. This prevents the possibility of clipping through the floor by capturing the Uproot too early or hitting the Uproot with Cappy without knocking its pot off by hitting it on the first frame after spawning.
• Capture frame teleportation has become possible.
• Attempting to capture an Uproot the moment it touches lava will no longer result in a softlock, and will instead simply result in Mario capturing the Uproot followed by the Uproot dying and forcing Mario out.
• Capturing a Hammer Bro just as a turnip is about to collide with it no longer results in a softlock (due to the Hammer Bro dying as it is captured), but now results in the Hammer Bro clipping through the ground.
• Coin duplication has become possible.
• Throwing Cappy while underwater will now register the cap throw to Archivist Toadette's achievement counter.
• A bug is fixed where respawning at a door while crouch walking toward the door would cause the door to repeatedly display the closing animation as long as the player crouch walks toward it.

Uses

Version 1.0.1 has identical uses to version 1.1.0, since the only difference between the two is that the latter features Korean language support. The two versions are the fastest for 3 Captures, slightly edging out version 1.0.0 since the clip through the ground near where the bridge lands in Cascade Kingdom can be used to collect Treasure of the Waterfall Basin a bit faster.

These two versions are faster than version 1.2.0 for Any% due to the possibility of Sphynx Clip and Turnip Clip, but slower than 1.0.0 due to the impossibility of using First Moon Skip to skip straight to the boss fight in Cascade Kingdom, and slower than 1.3.0 due to its fast loading times.
