RSDKv5U support for the Sonic Mania decomp is being deprecated
The Sonic Mania decompilation will soon be updated to remove support for running the game in RSDKv5U. This change is being made due to several upcoming fixes and ModAPI features for the RSDKv5U engine decomp that will make v5U Mania difficult, if not impossible, to support.
This change doesn't just affect the Mania decomp; it also affects GameAPI logic mods made for it, as mods built for one engine revision are not compatible with game or engine builds for another engine revision. As such, we are warning logic mod creators and end users of what this deprecation will mean to you and what you can do to prepare for it.
