Mushroom Kingdom Fusion and Super Mario Fusion Revival sources publicly released

Mushroom Kingdom Fusion and Super Mario Fusion Revival are now open source, with the source files for these projects available for anyone to download and modify. Anyone can edit and modify these source files, and even make their own revival of these projects. However, before you download either of these sources, please read the following carefully:

  • These projects were developed on Game Maker 8. GM8-made games do not run properly on most computers running Windows 8 or later.
  • Game Maker 8 is no longer commercially available by YoYo Games. If you want to continue development of these projects without porting them to GM Studio, a working copy of Game Maker 8 Pro is absolutely required. We will not give you a copy of Game Maker 8 Pro, so please do not even ask.
  • Porting these projects to Game Maker Studio and later is a logistical nightmare, which is why Fusion Gameworks did not attempt to port either of these projects to a later version of Game Maker.
  • Remember that you are taking a risk of having Nintendo come after you if you decide to put forth effort in reviving either of these projects.

Working on a fangame in the scope of these projects requires a lot of effort and dedication to see through. Ask yourselves these questions to give yourself an idea what to expect when taking on these projects:

  • Do you have any computer programming experience?
  • Do you know how to use Game Maker?
  • Do you have a decent grasp of game theory and level design?
  • Do you have access to external software needed to to make the assets, like a graphic editing program, audio editing program, etc.?
  • Can you gather people of different talents together to make these projects happen again?
  • Are you prepared to spend years working on these projects? These projects had multiple people working on them over many years, and they did not finish. If you will be working on them alone, even if you devote all your free time on them, you will easily spend years on these projects.

If after reading all that you still are committed to continuing these projects on your own, the download links are below. By clicking on the download links, you indicate you have thoroughly read all of the above disclaimers and assume all risks.

  1. Hmm… sounds like you guys have a lot to contend with.

    I wasn’t around during the tail end of the group failing because I had a LOT of other things in my life, but what resulted in the dissolution of the forum?

    1. Hey JDog, having a forum-only website was so old-fashioned. Additionally, the forum software is not mobile-friendly, and having a WordPress blog supplant the forums was planned for a couple of years, but we did not have the free time to implement the change until recently.

      I also want to move on from my hostile hotheaded angry era that I’ve finally addressed in my life. Untreated severe clinical depression can do that to a person if they are unaware of themselves.

  2. I am currently working on a big fan project of my own titled Mario Scattered Memories that takes place between Paper Mario and Super Mario Sunshine so may end up using some of the source files. There are a few similarity with MKF but much more differences. Link, Samus, and a couple others will instead be unlockable characters in my project using GM8.0. I will have no need for scripting actually.

    Once we find all the source files from the MKF developers, we will update this post with download links.

    Hi Guys,

    Just wondering if you’ve had any luck organising the source code for MKF?

    I enjoyed playing it back in middle school and really appreciate the effort you all put in to it.
    Was sad to hear when it got discontinued.
    Came across this blog and thought, maybe now that I know a bit more about coding I could give something back and have a go at furthering the game as a hobby.
    I realise this is a difficult task and expect it would take 6-10 years, but I still would like to try.

    Look forward to hearing back from you, and wish you luck with Mario Fusion.

    1. In the Game Maker 8 menu bar, select Resources > Select Extension Packages

      In the dialog box that opens, click the Install button.

      You will see another dialog box open showing the list of installed extension packages. Click the Install button here to bring up a file dialog box.

      In the file dialog box, select TextBox_Extension_V5.1.gex then click the Open button.
