Can someone explain how games this size are ported?

From what I know, developers use tools like Emscripten to compile the game's C++ source code into WebAssembly.

executables are very small in comparison to assets. you just decode the exe, transpile it to c, recompile again to wasm and viola!

you still need oryginal game to play

if u have the original game why on earth would u want to get a web browser involved? is there some benefit?m

Because they can. Why do people write new programming languages or operating systems when we already have more than we 'need'?

fair point. cyberpunk runs so slow on my pc that id expect running it in a browser will litterally make it cry. but i suppose i have a modernday potato to do stuff on :')
