A complete decompilation of Retro Engine v5 and v5Ultimate.

SUPPORT THE DEVELOPERS OF THE RETRO ENGINE

We do not own the Retro Engine in any way, shape or form, and this project would not have been possible had they not developed RSDKv5(U) in the first place. Retro Engine is currently owned by Evening Star; we highly urge you to follow & support their projects if you enjoyed this project of ours!

DO NOT USE THIS DECOMPILATION PROJECT AS A MEANS TO PIRATE SONIC MANIA OR ANY OTHER RSDKv5(U) GAMES.

We do not condone using this project as a means for piracy in any form. This project was made with love and care for the source material and was created for purely educational purposes.

Additional Tweaks

• Added a built-in mod loader and API allowing to easily create and play mods with features such as save file redirection and XML asset loading, supported by all sub-versions of v5U.
• Added a built-in shader compiler for backends/platforms that support it.
• Added various other backends to windows aside from the usual DirectX 9 backends

How to Build

Get the source code

• Clone the repo recursively, using: git clone --recursive https://github.com/Rubberduckycooly/RSDKv5-Decompilation.git or if you've already cloned the repo, run inside: git submodule update --init

Follow the build steps

• Windows
• Mac
• Linux/Switch
• Android

Other Platforms

Currently, the only officially supported platforms are the ones listed above. However, the backend is very modular, so the codebase is very multiplatform.

However, since release, there have been a multitude of forks made by the community (keep in mind that many of these ports are still a WIP!:)

• WebASM by heyjoeway

• New 3DS by SaturnSH2x2

• Wii U by Radfordhound

• Wii U by Clownacy

• Vita by SonicMastr

• and a general optimization fork by smb123w64gb
