Recompiled Fate/unlimited codes (PS2) into a native Windows port with Claude

The FUC Community project aims to create a 100% native Windows version of the PS2 release of Fate/unlimited codes. The method involves static recompilation of the game's executable using PS2Recomp, which translates the original code into native instructions. A custom native renderer replaces the PS2 graphics path, converting RenderWare and game-specific semantics into a Common Render IR that targets a Windows Vulkan backend. The project documents progress through aggregate figures and census data, tracking the state of effect programs and battle routes. As of October 2026, the project reports 99.81% coverage for measured battle routes, though most game areas remain unmeasured. The author notes that 0% native coverage for effect programs indicates that runtime execution has not yet been recorded, rather than an absence of native functionality. Development is ongoing, with Claude Opus 5.5 credited as a co-author on documentation and progress reporting. The project maintains a repository at https://raw.githubusercontent.com/elprogramadorloco-arch/fuc-community/HEAD/README.md.
