Super Mario: Star World

Super Mario Star World is the upcoming remake of Super Mario Star Road, one of the most popular SM64 Hacks, being developed by SKELUX. In addition to the improved graphics SM64DS provides, Super Mario Star World will have much more content than Super Mario Star Road.

SKELUX aims to make this one of the largest Super Mario titles of all-time with more Power Stars than any other Mario game. This was hinted at in Mario's Holiday, as one of the Signposts of Future Predictions reads the following: "So many Power Stars....More than Mario has ever collected?".

SKELUX will be replacing all vanilla content with new features, such as restyling Blue Coin Switches to look like P-Switches, replacing Switch Power Stars with purple !-Switches that spawn platforms and Power Stars and making Red Coins act totally different.

Mario's Holiday
Main article: Mario's Holiday

Mario's Holiday is a demo/prequel for Super Mario Star World, which has a hub area called the Sky Land Resort VIP Area, two main courses called Frosty Fair and Bob-omb Cruiser, and one side course called Starry Grasslands. Mario's Holiday has 26 Power Stars. However, there may be more as SKELUX hinted at the possibility of more being hidden, this is very unlikely though.

Mario's Detour
Mario's Detour is going to be an upcoming demo for Super Mario Star World. This demo is a sequel to Mario's Holiday.

Arc 1
Super Mario Star World is broken up into two arcs with the first being the story taken from Super Mario Star Road.

It is unknown what has been changed from Star Road's story, or how it connects with the second arc.

Arc 2
The second arc, taken from the canceled game Super Mario Star Road 2, which SKELUX was making before incorporating its story arc into Super Mario Star World, has been announced since the early summer of 2018, but has been in the plan for more than a year earlier. It is currently unknown how many courses will be in the second arc.

The second arc's and the game's overall final boss, SKELUX's avatar, a Chain Chomp, is said to be quite literally the largest boss ever in any Mario game, also having the ability to teleport. It might be the threat that was hinted at in Mario's Holiday, as one of the Signposts of Future Predictions read the following: "A new threat....The entire world, could it be in danger?" This might also mean that more than the Mushroom Kingdom will be affected in the game. The second arc will have two endings instead of one. Neither of them will be good, but, rather, one will be bad and the other will be sad, but less bad.

Controls
New controls present in Super Mario Star World include rolling from Super Mario Odyssey, which replaces slide-kicking and underwater ground-pounds.

Playable Characters
The player starts their journey as Mario, although Luigi and Wario are also playable characters in Super Mario Star World, but they aren't available from the start of the game, as one of the Signposts of Future Predictions from Mario's Holiday read the following: "Luigi....Oh no, he is trapped somewhere!" This location is unknown, but in the preview of the level Frosty Fair from Christmas 2014, the player is seen collecting a Luigi key after defeating Chilly Chomp, a new boss in the game.
 * Mario
 * Luigi
 * Wario

There is a chance that another playable character will be appearing in Super Mario Star World, though it is unknown who they are. One of the Signposts of Future Predictions from Mario's Holiday read the following: "Someone else....They look a bit like Mario, or Luigi....Who could it be?".

New and Improved Power-Ups
The following Power-Up Switches are confirmed to be returning:
 * Red Switch (Wing Feathers)
 * Green Switch (Rainbow Stars)
 * Blue Switch (Vanish Mushrooms)
 * Yellow Switch (Unknown)

Wing Feather
The Wing Feather from Super Mario 64 DS will return, behaving the same as in the original game. Wing Feathers will be obtained from Red !-Blocks, which will become solid after the Red Switch is pressed.

Rainbow Star
Once again, another classic power-up shall be returning. It is the Rainbow Star from the Super Mario Galaxy Series, which will be replacing the Metal Cap from Super Mario 64. It will have the standard invincibility and speed boost, but now gives you the ability to walk on water that Luigi had in Super Mario 64 DS. Rainbow Stars will be obtained from Green !-Blocks, which will become solid after the Green Switch is pressed.

Vanish Mushroom
The new Vanish Mushroom turns you transparent, which will be replacing the Vanish Cap from Super Mario 64 but with the same abilities, such as passing through certain walls. Vanish Mushrooms will be obtained from Blue !-Blocks, which will become solid after the Blue Switch is pressed. However, SKELUX also stated that he designed it with eyes because it is a different power-up than the Boo Mushroom from the Super Mario Galaxy Series.

Double Cherry
The Double Cherry will be making a reappearance from Super Mario 3D World. They will create a clone of the player and they behave similarly to those from said game. The way of obtaining the Double Cherry is currently unknown. However, one of the In-Course Areas, the Clone Chamber, which is located in Starlight Runway, features a cloning mechanic that is very similar to the mechanics of the Double Cherry. A preview of the Clone Chamber on YouTube shows Mario creating a clone of himself by hitting a light blue ?-Block, but doesn't show him grabbing a Double Cherry.

Mega Mushroom
The Mega Mushroom from Super Mario 64 DS will make a reappearance, and will work like in the original game. The way of obtaining Mega Mushrooms is currently unknown.

Yoshi
There will be modified rideable Yoshis in the game, which will be replacing his playable role. Different colors of Yoshi will be in the game and will be found in colored eggs. The way to obtain the various Yoshi eggs is currently unknown. Each various color Yoshi will have unique abilites, similar to those from Super Mario World.

Modes
There are going to be several new modes including:
 * Introduction Mode: the introduction to the course with backgrounds, models, weather, and Power Stars being changed.
 * Classic Mode: a Super Mario Odyssey-like collect-a-thon without filler Power Stars or ones that take you out of the level.
 * Time Attack Mode: a score based mode in which the player aims to collect as much points as they can within the time limit of 1 minute, the player can increase this timer by gaining points. This mode also acts as the replacement for the 100 Coin Stars.

Courses
Note: this list is incomplete as not every course has been revealed yet.

Secret Courses
° These courses were planned to be in Super Mario Star Road 2, but SKELUX cancelled the project and wanted to include the story and courses for Star Road 2 in Star World.

Costumes
Costumes for Mario to change into will be present in Super Mario Star World, as one of the Signposts of Future Predictions from Mario's Holiday read the following: "Costumes....Mario learns some fashion sense!" However, it is unknown if costumes can be found and/or purchased through means other than the Shop.

Shop
There's going to be an Item/Costume Shop where players can spend their coins and lives in exchange for items and costumes. Additionally, coins and lives are also saved, and maximize at 9,999 and 99 respectively. It is currently unknown where the Shop will be and what items will be up for sale.

Minigames
SKELUX has stated that he has considered planning and adding in 10 new and modified unlockable minigames playable through arcade machines. These will have themes based on the courses that they are unlocked in, such as the Chucking Competition from Chuckya Harbor.

Graphics Streamlining
SKELUX has implemented a feature into the game called Graphics Streamlining, which enables maximum quality backgrounds and textures for emulator and PC users and the highest possible quality textures, even next-generation ones, for hardware users.

Trivia

 * Development on Super Mario Star World has gone on for more than 8 years while Super Mario Star Road was finished in 2 years.
 * Super Mario Star World features the Anti-Cheating System, where the game won't allow any cheat to be used. The main reason for this was to prevent people from using it to find big secrets and stealing the game's assets without permission.
 * Super Mario Star World will have one Main Course more than most other SM64DS Hacks. This was hinted at in Mario's Holiday, as one of the Signposts of Future Predicitons read the following: "A 16th stage....A large new world will be visited?"
 * Mario's Cap might not be available from the start of the game, as seen in multiple screenshots and YouTube previews. It might have to be recollected in Creepy Coast Cave, as shown in an image, which would make sense as something will have to replace the purpose of said area due to the Green Switch being in another location.
