Super Mario World: Just Keef Edition

Hack of Super Mario World


Bensalot AKA Just Keef Presents

Super Mario World Just Keef Edition

It’s the classic game with updated graphics,additional enemies and Dinosaurs, new tricks traps and paths, updated mechanics, and all new surprises along the way. Mario and the gang have decided to take a break from adventuring only to find that there is yet another adventure to be had! It’s the same old story, Bowser kidnaps the Princess blah blah blah.

This is a re-imagining of the original game with sort of a Lucas twist. Now Dinosaur Land actually has a wide variety of Dinosaurs, Luigi is his own man and not just a color swap of his brother, Toad joins the adventure with tips and useful item stops, all new original levels, and much much more! Feel like reliving the fun of Super Mario World with some added challenge? Give this hack a whirl. It’s a BLAST FROM THE PAST!

NOTE: There are 2 different versions of this patch. There is the main game with 2 players. Player 1 and Player 2 are both controlled with 1 controller so that the game can be played 2 player on mobile devices or just to use both Mario Bros. The second patch is the same game with the ability to select Mario or Luigi from the start menu. This patch will only allow for one player. Also, when I submitted 1.2 the changes only took effect in the main patch so this has been corrected.

Version 5.0

  • Altered the speed of Tyravonous Rex and Leolapleurodon. TRex is now a bit faster and Lpleurodon is a bit slower. This helps balance the levels a bit more.
  • Some more spawning fixes
  • Luigi graphics slightly more altered
  • Crystal Secret 1 has been altered to reduce spamming of enemies with the addition of the new dinos. The secret exit in the level is also a bit trickier.
  • Save files have had their names changed from Mario to Game

The name almost kills it... but it's still great.

Very nice hack.

Love everything.

But, what’s up with the name? Just Keef Edition? I have no clue what this is referring to, and it feels like an inside joke which is kinda lame when you want to use this as your main way of playing a timeless classic. Even the title screen feels slightly ruined with the weird name.

I’m thinking many people will not download it because of the name as well. It doesn’t sound like an improvement hack, but more like some guy named “Keith/Keef/Whatever” just made his own crazy hack. But this is a legit main version of a classic game, and in many ways a serious improvememnt.

Besides the name, which I really dislike, it’s a great hack.

EDIT: I’m not sure if I completely understand the difference between the two versions of the hack.

Version 2.2 Recommended - Yes
