Item Edits

Almost all the items have been changed to make the racing experience more chaotic. In addition, several brand new items have been introduced.

Item Edits
Item Feature Author Information
All Items All Items Can Land MrBean35000vr, CLF78 Every item (with the exception of the Thunder Cloud, POW Block and Lightning) can land on the floor when dropped and be activated when a racer drives over it. Item effects are identical to if the user actually fired the item themselves.
Disable Item Poof CLF78 Prevents items from being removed by the game for being on the track too long. Items will still disappear after a while due to Item Limits being reached.
Dynamic Item Sizing CLF78 Projectile items will reflect the status of the player who dropped them. If used while in a Mega Mushroom, they will remain giant, and if used while shocked they will remain tiny. For Bob-ombs and Blue Shells, this also affects their explosion radius.
Instant Item Boxes Anarion Item boxes respawn instantly to allow everyone to get items.
Max Item Limit Modifier CLF78, Ismy Increases the amount of items that can be in play to make for more chaotic racing. The new limits can be found here.
Newbie Helper CLF78, Seeky If a player is lapped by first place, they will no longer pull Bananas, Shells, Fake Item Boxes or Bob-ombs. CPUs are not affected by this code.
Remove Mushroom Bug Vega The Mushroom bug is a "feature" implemented in the game to give you a Mushroom for your 16th, 18th and 20th+ item, regardless of your position. This code removes it.
Remove Mushroom When No Item Available CLF78, Ismy The game no longer replaces an item with a Mushroom if said item's limit has been reached (except for the POW Block and Lightning, which give Triple Mushrooms instead).
Ultimate Item Randomizer CLF78, Ismy Completely randomizes item chances and gives a (weighted) random amount of the chosen item (see here for more info). It also randomizes the items spawned by objects, such as leaf piles, wooden boxes and Goombas. A few rules remain to make the gameplay more balanced:
  • Blue Shell, Lightning and POW Block timers are still respected.
  • CPUs cannot pull Feathers and cannot pull Blue Shells and POW Blocks when in first place since they are not able to use them correctly.
  • Lightnings, POW Blocks and Thunder Clouds cannot be pulled from objects.
Green Shell.png
Green Shell
Green Shell Speed Modifier davidevgen Green Shells move at 2× speed.
Shells Never Break CLF78 Green and Red Shells will only break by hitting a player, an object or another item. Red Shells will still break on walls if they are actively chasing a player.
Red Shell.png
Red Shell
Red Shell Targeting Modifier CLF78 The Red Shells' targeting logic has been altered in the following ways:
  • Shells will only target the player in front of the shooter, rather than targeting players in higher positions indiscriminately.
  • Shells will not skip a target even if said target is getting hit by another item.
  • Shells thrown from first place will not target anyone.
Banana Damage Modifier Skullface Bananas make the player spin for a longer amount of time, slowing them to almost a halt.
No Item Use Stun CLF78 Running into a Mushroom, Golden Mushroom or Star while getting hit will still apply their effect.
Golden Mushroom.png
Golden Mushroom
Motion Sensor Bombs Hamster35000vr Bob-ombs only explode when someone gets close to them.
Blue Shell.png
Blue Shell
Blue Shell Speed Modifier mdmwii Blue Shells' traveling speed has been increased to 4×. However, they can still be dodged with Mushrooms.
Draggable Blue Shells Luis Blue Shells can be held behind you like Red Shells. They will explode on contact, but not hurt the player. They can be used to protect against other items being shot from behind, but if the player gets wheelie-bumped while holding a Blue Shell behind, it will fall on the ground.
Objects Ignore Lightning Damage CLF78, Ismy Track objects such as Goombas, penguins and crabs are no longer affected by Lightning.
Shock Squishing CLF78 If a shrunk player and a normal player bump into each other, the former will be squished (but will not lose their item and will not experience hit-stun).
Mega Mushroom.png
Mega Mushroom
Mega Flips Everything JoshuaMK Trucks and Chain Chomps will flip over if hit with a Mega Mushroom (instead of stopping the player).
Mega Mushroom Size Modifier CLF78, TheLordScruffy The player's size when in a Mega Mushroom is 1.5× the original. The camera FOV is slightly increased to adapt to the new size.
Feather Item CLF78, stebler The Feather, which replaces the Blooper, lets you trick off the ground and jump high in the air. Additional features include disabling invisible walls and fast falling (both while airborne).
POW Block.png
POW Block
Fast POW mdmwii The POW Block hits at the second strike instead of the third one to catch players by surprise.
No POW Delay Ro If a POW is used while another POW is about to strike, the POW will be reset. This can be used to confuse players.
POW Yourself in 1st CLF78 If a player uses a POW while in first place, they will POW themselves.
Thunder Cloud.png
Thunder Cloud
Impervious Thunder Cloud CLF78 Thunder Clouds no longer disappear when using a power item or entering a cannon.
Mega Thunder Cloud _tZ The Thunder Cloud gives a Mega Mushroom effect, instead of shrinking the player.
Bullet Bill.png
Bullet Bill
Bullet Bill Cannon Speed Modifier CLF78, Ismy Players in a Bullet Bill move faster than normal players in cannons.
Bullet Bill Speed Modifier davidevgen, CLF78 Bullet Bills move at 220 km/h, making them the most valuable item in order to catch up to other players.
No Bullet Bill Icon Anarion Once you use a Bullet Bill, its icon in the roulette goes away, allowing you to pick up and use another item while in it.

Item Data

Item amounts are determined separately from item pulls. The chances of pulling a triple item in a distribution is the pulling chance × the amount chance. Object-spawned items will always be single.

Known Bugs

  • Although officially supported, split-screen multiplayer compatibility is poor and prone to bugs/crashing.
  • Bob-ombs generated by objects offline will not blow up unless hit. They will also slide on slanted surfaces, although very slowly.
  • Currently, the NTSC-J version crashes upon track load.
  • Due to a conflict with the Wiimmfi payload, Ultra UnCut will fail after going online.
  • If a player has multiple Thunder Clouds, and a Thunder Cloud's mega effect ends while another has yet to strike, off-road invincibility will be deactivated.
  • In the NTSC-U version, the score screen during an online race is accidentally skipped.
  • Memory-intensive tracks may cause items and objects to lose their collision or disappear altogether.
  • Players who skip key checkpoints online using the Feather will cause their position to desync.
  • Shock Squishing sometimes still activates despite being already squished.
  • Show Time Difference tends to break quite easily and therefore show an incorrect time. This is especially common with the "Player in Front" option.
  • The game may enter an infinite loop and crash when too many items are on track. This only seems to occur offline.
  • The regular boost speed is slightly off the original values until the player uses a Bullet Bill or enters a cannon. The bug can be restored by respawning.
  • The resized explosion hitbox does not match the resized visual 100% of the time.
