Super Mario Star World is an upcoming SM64DS ROM Hack. As a remake of Super Mario Star Road, it is being developed by SKELUX and is being developed for the Nintendo DS rather than for the Nintendo 64. In addition to the improved graphics supported by Nintendo DS, Super Mario Star World will have much more content. It is currently under development, but the project can be found here.

Development on Star World has gone on for more than six years; while Star Road was finished in four.

SKELUX has stated he plans to add 10 new and modified minigames, as well as modified, colored Yoshis - each having unique abilities, similar to Super Mario World (blue Yoshi's may be able to fly, etc.)

Other new features: Rolling (from SMO, replaces slide-kicking), Underwater Ground Pounds and New Gamemodes (Intro, Classic and Time Attack mode, with Intro being the introduction to the level, with level models, stars, backgrounds or weather being changed, Classic being an Odyssey-like collectathon without filler stars or stars that boot you out of the level and Time Attack being the replacement to the 100 coin stars.)

As for planned features, SKELUX has started work on the new 16th Course, a city themed level, by composing a 4-minute song that matches it's theme.

This will be one more course than any standard Super Mario 64 (DS) game or hack. SKELUX aims to make this the largest Super Mario title of all time with more stars than any other Mario game (including Super Mario Odyssey's 999 moons) (making it at least 5-10x bigger than the original Star Road), and also replacing all vanilla content with new features, such as replacing switch stars with purple ! switches that spawn platforms and stars, making red coins act totally different and changing almost every enemy to be Paper Mario or Super Mario 64 styled.

It is broken up into two arcs with the first being the story taken from the original Super Mario Star Road and the second from the canceled game Super Mario Star Road 2 which Skelux was making. This second arc has been announced in the early summer of 2018, but has been in the plan for more than a year earlier.

The second arc's and the game's overall final boss (the chomp on SKELUX's avatar) is said to be the "quite litterally the biggest boss ever in any Mario game", having the ability to teleport. Arc 2 will have two endings instead of one. Neither of them will be good, but rather bad and sad but less bad.

SKELUX also optimized this hack quite a bit, making it playable on a real DS without noticeable lag. His goal is to push the DS to it's limits.

This game also has a feature called Graphics Streamlining, which enables max quality textures and backgrounds on emulator users and highest possible textures for hardware users.

There is also an items shop found later in the game, where you can use your coins and lives for items. Additionally, the lives and coins are also saved, and can go up to 99 and 9999 respectively.

The game also features the anti-cheating system, where the game will not allow any cheat to be used. The main reason was to prevent people from using it to find big secrets and to stealing game codes without permission.

The demo/prequel for Star World is called Mario's Holiday which has 2 levels (Frosty Fair, Bob-omb Cruiser), 1 bonus level (Starry Grasslands) and a hub area. It has 26 stars however there may be more as SKELUX hinted at the possibility of more stars being hidden.

New & Improved Power-Ups


Double Cherries

The Double Cherries will be making a reappearance back from Super Mario 3D World, they will make a clone of the player appear and behave similarly to the ones in 3D World.

Rainbow Star

Once again another old power-up shall be returning: it's the Rainbow Star from the Super Mario Galaxy series! It will have the standard invincibility and speed boosts, but now gives you the ability to walk on water that Luigi had in SM64DS.

Vanish Mushroom

A new Vanish Mushroom that turns you transparent replacing the Vanish Cap but with the same abilities such as going through certain walls. However, Skelux also stated that he designed it with eyes because it is a different power-up than the Boo Mushroom power-up found in Super Mario Galaxy.

Mega Mushroom

The Mega Mushroom from New Super Mario Bros will make an appearance replacing the Super Mushroom and working like in the original Super Mario 64 DS and New Super Mario Bros.

Gold Flower

The Gold Flower may be making an appearance in the game, but it is highly unlikely now that SKELUX has introduced underwater Ground Pounds.

Wing Feather

The Wing Feather will also return behaving the same as in the original game.


There will be a rideable Yoshi in the game, which will be replacing his playable role. Different colors of Yoshi will be in the game and found in colored eggs. The way to obtain the eggs is currently unknown.

Mini Games


Skelux has considered adding new unlockable mini games playable through arcade machines. The minigames will have themes based on the levels they're unlocked in such as the Chucking Competition from Chuckya Harbor.

Streamlining Graphics


SKELUX has implemented a feature into the game called graphics streamlining. With it, on PCs, he can turn the textures into high quality ones (see image) and next gen ones on hardware.
