Error:

From the comment in SDL_filesystem.h:
Please call SDL_free() on the pointer when you are done with it

When building the project with MSVC, I ran into some debug heap asserts early into the program startup.
The culprit appears to be the code in m_config.c that does free(prefdir) as changing these to SDL_free(prefdir) resolved the issue.

I'm not sure what to do about `GetDefaultConfi

When opening a package of any kind, it'd be nice to have an option that shows only the package name instead of the full path. Simply put, people may have a long filename and that makes it more difficult to tell which file belongs where, especially if they have the same name.

I often get lost wandering around the source code understanding how it works. It would be nice to describe what the source file was for just like in chocolate-doom's source files.
