Case study

XI on Anything: statically recompiling FINAL FANTASY XI clients

XI on Anything recompiles FINAL FANTASY XI's 32-bit x86 FFXiMain.dll and FFXi.dll to C from the user's installation and runs them through a native game host. Its platform layer supplies graphics, audio, input and sockets across desktop and selected mobile or console targets. A LandSandBoat server provides sign-in and gameplay services.
