# Super Mario World (SNES): Super Mario World statically recompiled to native C, with some AI help > Source: > Published: 2026-11-10 08:57:02+00:00 ## Evidence at a glance Based on the linked sources. The author's reported result and independent confirmation are separate checks. - AI involvement - Reported models: Claude Opus 5. Tools: snesrecomp, LakeSnes-derived core. The writeup below describes the work attributed to AI. - Reported result - Partial. This is the directory's source-based outcome classification. - Independent confirmation - Not reported. - Human work and limitations - Matthew Stanley (mstan) writes most commits himself and says his time for any one title is limited. The README asks for testing and pull requests and warns of rough edges. ### Original sources ## What was done Matthew Stanley's Super Mario World port is a proving ground for his snesrecomp framework. Twelve of 158 commits carry a Claude Opus 5 trailer, so the AI share is smaller here than in other entries. SuperMarioWorldRecomp statically translates the 65816 CPU code of Super Mario World (SNES) into C using the snesrecomp framework. Every function the game runs on the main CPU becomes a generated C function under src/gen. The rest of the SNES, meaning the PPU, the SPC700 audio processor, DMA and HDMA, is not recompiled but run through a C hardware reimplementation derived from LakeSnes, which the README says is the same model other static-recompilation projects follow. The author describes this repository as a byproduct of building snesrecomp, where the games are the proving ground. It is labelled an in-development preview. The README says it is believed fully playable and hand-verified through Yoshi's Island (including Iggy's castle boss), Donut Plains from start to finish, and part of Vanilla Dome, with no catastrophic visible regressions in those worlds. The README links a post called Recomp and AI: 5 Months Later for background. On evidence of AI use, twelve commits carry a Claude Opus 5 trailer out of the 158 in the history window, and the repository has agent instruction files. The author's own commits dominate, so this is human-led work with some AI assistance rather than an AI-driven port. ## Reproduce it Download a release for Windows or Linux, then point it at your own legally obtained Super Mario World (USA) ROM (.sfc or .smc); the path is remembered in rom.cfg.
