Case study

xmen2-pc: a matching decompilation and native port of X-Men 2: Clone Wars

xmen2-pc reconstructs X-Men 2: Clone Wars as handwritten C and ports it to Windows and Linux without 68000 emulation. Its workflow uses a byte-matching disassembly, static recompilation and the original Apple MPW C 3.3 compiler; the author reports machine-code matches for 3,047 C functions and instruction-level comparisons for 117 assembly functions. The port loads graphics, sound and levels from the user's ROM and adds widescreen play, higher display rates and rollback netplay.

Requirements & limits

Prerequisites: Requires the user's own USA/Europe X-Men 2: Clone Wars ROM with SHA-1 61409e6cf6065ab67d8952b891d8edcf47777193.
Prerequisites: Runs on Windows or Linux; the Linux release needs SDL2.
Limits: Three- and four-player modes have been played less than the rest; display pacing is experimental and has not yet been measured on a live display.
License: The project's original work is MIT licensed.
License: The included segagenesisrecomp component uses PolyForm Noncommercial 1.0.0, so builds of the port may not be used commercially.
