Super Mario World: The Definitive Edition is a ROM-Hack of the original Super Mario World game on the Super Nintendo Entertainment System (SNES). It was made originally as a remaster of the Super Mario World Plus hack which was released in May of 2024. Definitive Edition started progress in early 2025 around February.

The hack is meant to add bugfixes from the original game, add all new content (from things such as SMAS+SMW, Super Mario Advance 2, the Super Mario Maker series, the VLDC ROM-Hacks by SMWCentral, and prototypes themself of SMW) such as course themes, music, sprites, level structures, features, and others. There are also a couple extra new things that were added which were never originally in any adaption of SMW. More info can be found in the changelog.txt

The hack is inspired by many things such as SMAS+SMW, SMA2, SMM series, VLDC hacks, SMW protos, SMW Remastered, SMW 30th Anniversary Edition, SMW Just Keef Edition, SMW Redone, IsoFrieze/Dotsarecool romhacks, the New Super Mario Bros. series + SMB Wonder, and MaternalBound 2 Redux.

Note: for an in depth look at all the features and alterations you can check out the included changelog.txt file for reference. At the source link someone made a highly praising review of this hack that gives it more justice than I could. If you're curious, I'd suggesting checking it out.

A little disappointed, I don't think I will ever get my true definitive edition of Super Mario World, my ideal definitive edition will have to add the opening cutscene from the GBA, playable Luigi in single player complete with his move set and improved sprites from the GBA (Press R to swap between characters in world map), the ability to save at any time, reaching a checkpoint as mini Mario gives you a mushroom, all of the Japanese cut content like the sub title screen and the ability to eat dolphins as Yoshi, and heck maybe bring over the voice overs, basically I want all of the quality of life improvements from the GBA version with the bigger screen and colors of the SNES.

When Luigi is not just a palette swap of Mario.

Like Final Fantasy V and VI GBA version with music and graphic restoration mod so it would look like SNES version but with additional GBA contents.

Once was a game that was perfect.
Now it's perfecter.

I hope somebody uses that hack as a bases and builds on it, I tried it with RetroArch and core SNES 2005 and played a few levels with no issues but the warning screen at the beginning does make me worried that I hope somebody can take it and improve upon it, add some more polish, make the character switching instantaneous like in the GBA, add the ability to save anywhere, allow you to skip the intro, add a growing animation when touching a checkpoint as mini Mario, and have an option for the voice overs (for nostalgic reasons).

This.
The opening cutscene in 30th Anniversary edition is cool the first couple of times, but I usually just want to jump straight into the game. Saving anytime or after each level is also a much needed qol feature. Personally, I prefer to not have the voices, but I can understand some are nostalgic for them.

Using the GBA version as the base for a definitive version hack seems like it'd be the best way to go imo. As for a bigger screen you could just run whatever emulator you're using in fullscreen. I've always personally been more of a handheld gamer than a console or PC gamer. Mostly due to what I had available but I still tend to gravitate towards handheld stuff even now. I used to have SMW GBA but I lost the cart somewhere and have never been able to find it. I figured this hack was more of a miss than a hit, but I still posted it anyways. At the very least recreating that cover completely from scratch using Photoshop helped me sharpen up my image editing skills. You should check out the original boxart from the romhackplaza page, it looks like crap in comparison to my redone one. (although it's still kind of a lame cover, at least it's not AI)

I too grew up with the GBA version, pretty sure I still have the cartridge though the battery more than likely died a long time ago.

I suppose making a hack for the GBA version might be the easier option, this is a similar case to games like Sonic Chaos and Mega Man & Bass where despite growing up with the handheld versions I just play the console version nowadays so I don't have to deal with the screen crunch.

The 8bit Sonic games are very similar to the GBC/GBA Mario remakes, you get more polish and extra content with the exchange of severe screen crunch, it's like pick your poison, I wish for an all in one hack

In my opinion, the definitive version is the 30th Anniversary Edition, which you can find on this same site.
It not only has the GBA intro and sprite improvements, but also much more content and secrets with SNES graphics and sounds.

Didn't know about that, I might check it out, thanks.

I took your advice and gave it a try, in my opinion THIS deserves to be called Definitive Edition, I mean you don't get to save anywhere like in the GBA version and you don't get the voice overs (which depends on who you ask might be a good thing) but aside from that it seems to have everything I wanted, GBA intro, playable Luigi complete with his move set and sprites, character swapping in the overworld, even the checkpoints give you a mushroom, dude it even has the Mario Bros. arcade game like in the GBA, how did I not know of this hack? Thank you so much

The author of this hack probably is wasting his time tbh. It's like how there's too many improvement hacks for gen 1 to 4 Pokemon games. I guess they can be passion projects for the hackers, but more than half the time they're just redundant

Is there a version that adds both the GBA content, and the MSU-1 music?
