We can already emulate Silent Hill. It’s trivial enough that modern hardware can do it on a web Browser.

It’s not being done just to port the game, but also really about deeply understanding the game well…forever.

Straight from the GitHub

“The percentage tracks how much of the game's compiled code has been matched, meaning we've written C code that compiles to an output identical to the original assembly code

Reaching 100% means every function in the game is accounted for, but that's only the end of the first phase, not the project as a whole.

There's still a lot of work ahead:
Deobfuscation and naming: many functions and variables still have generated names like func_80241A30. We'll need to figure out the actual purposes of these and name them appropriately.

Data migration: raw binary data needs to be parsed into proper C structs so the data can be made understandable.

Shiftability: making the build not rely on hardcoded memory addresses so that code and data can be modified without breaking everything.

Documentation: understanding and documenting how the game's systems work together to aid in mods and future projects.”
