HELP: Cave Story - Game Engine Architecture?

How does the Cave Story engine work under the hood? (freeware version)
What are the main classes and how do they interact?
How does TSC bind itself to C++ and interact with the game engine?
How the Entity Component System is structured in the game?
Thank you ^^

 

If you have a copy of CSE2's source code, that should have all the answers you're looking for

It does look really interesting.
How faithful it is to the original source?

 

It practically is source code.

 

The "accurate" branch is 99% the original source code. Other branches swap out libraries such as for rendering and audio behind the scenes, but the TSC and entity functions would still mostly be the same between branches anyhow.
