Is not having LLE Modules the reason why most games freeze?

What do you mean AppVeyor builds break games? The AppVeyor builds are compiled using CMake and the Visual Studio compiler, so there shouldn't be any problems.

Should probably make another thread with logs in support, but games like Terraria, Comix Zone, and others listed in the "Playable" and "Loadable" don't seem to work at all or try to load and crash?

No matter if I set the LLEs that It had the previous build it just breaks it.

I never seem to get anywhere unless I use the second interpreter on both cpu and gpu either, but that's just me.

Were you trying to run the games with the recompiler? Also, if the games no longer work, provide the logs and other necessary tidbits and it'll be moved to the right section.
