# Marvel vs. Capcom 2: matching PS2 decompilation and browser port

> Marvel vs. Capcom 2 reconstructs the NTSC-U PS2 game's code as C checked byte for byte against the retail executable, then compiles that code for a WebAssembly and WebGL2 port. The author reports 99.93% code coverage, a byte-exact ELF rebuild and end-to-end browser play; desktop ports are planned.
