Sonic '06 Randomiser Suite

An all in one software suite for randomising various elements in Sonic '06 on the Xbox 360 and PlayStation 3.


To build the Randomiser Suite, simply clone the project and its submodules using a git based solution (such as GitHub Desktop) and open the MarathonRandomiser.sln file in a recent version of Visual Studio (anything supporting .NET 6 should work fine, all the development was done using versions of Visual Studio 2022) and then compile it as normal, if the build fails it may be due to missing Nuget Packages, as the project uses Marathon for interfacing with Sonic '06's file formats, HandyControl for much nicer looking UI controls, Ookii Dialogs for better file and folder browsing and SharpCompress for extracting Voice Pack zip archives; ensuring that all four of those are present and accounted for should resolve any compile errors. Also check that XNCPLib and Amicitia.IO are both building as well, as they are needed for the User Interface Randomisation.

Compile warnings will be thrown regarding Possible null reference arguments and Dereferences of a possibly null reference but both of those have never caused any problem for me.


For a proper run down on the features and information on configuring and using the Randomiser Suite, check out the Wiki. For the basic functionality, see below.


Object Placement Randomisation

Randomisation of various elements within '06's Object Placement (.set) files, these are:

  • Enemy types and their behaviours

  • The characters that get used in stages

  • The contents of item capsules

  • Types of props

  • Voice lines that play throughout gameplay

  • Types of doors

  • Object draw/activation distance

  • Miscellaneous cosmetic details

  • Types of particles

  • Use of an unused jump board

  • Shuffling object positions

  • Duplicating enemies

A lot of the Object Placement features can be further randomised, see the Wiki for more information.
