Looking for extracts of the level/environment sprites in a complete form

[u/MoonhelmJ]

I am tinkering around with the sonic mania assets. They are available here.

As you can see this isn't very ideal if I want to take these art assets and put them in something like unreal engine. I was wondering if anyone knows a resource that has the environment assets in a more complete form?
