What is a .RSDK file?
An RSDK file is a special type of file that acts like a storage box for video games made with the Retro Engine, particularly Sonic games like Sonic CD and Sonic Mania. Think of it as a big container that holds everything the game needs to run properly. Inside this container, you can find all sorts of game files, including 3D models (which are like the shapes and characters you see in the game), sprites (which are the 2D images or animations), and various configuration and scenario files (these are .BIN files that tell the game how to behave and what to do in different situations).
To open an RSDK file, you can't just use any program. There are specific tools designed for this purpose. One such tool is called "rsdkunpack," which helps you unpack or open up the RSDK file so you can see all the different pieces inside. Another set of tools is known as "Sonic Mania RSDKv5 Tools," which is specifically tailored for working with RSDK files from Sonic Mania, allowing you to explore or modify the game's assets. These programs are essential for game developers or modders who want to create new content or change existing content in Sonic games that use the Retro Engine.
