How is this possible? According to the GitHub[0] README:

> The game's x86 code is translated to C ahead of time and compiled to WebAssembly.

So they decompiled the x86 into C which was fully able to be recompiled to WASM?

I'm also not sure of the legal repercussions...

The game asset is the clear copyright violation, even if the code might be considered a "clean reimplementation" (but this is obviously a derivative work, so definitely not clean).
