Sonic Mania

What works

The game runs smoothly. While it runs on a clean wine prefix i'd recommend installing the vcredist and directx installer since the game depends on them on the special stages and the 3D effects.

Here's a list of what was tested;
A full Sonic & Tails run with all Chaos Emeralds and good ending.
The Knuckles Specific Levels (The Beginning of Green Hill Act1, Mirage Saloon Act1 and Lava Reef Act2)
Time Attack Mode (To Flying Battery.)
Encore Mode (To Flying Battery.)
Co-op

Additional Comments

The mod loader can also be run as well. I couldn't get Mono to work with it so i installed .Net 4.7.2 and that seemed to do the job. But you need to set d3d9 to native or native, builtin on WineCFG for the mods to load.

About modding the game instead of playing mods. Maniac Editor runs fine no extra steps. The RSDK Animation editor i couldn't get it to run. ManiaHex runs but if you click on anything its just a black screen.

ManiaPal doesn't start up.
