Super Metroid (mstan)

Game: Super Metroid → (SNES / Super Famicom, 1994)

A recompilation of Super Metroid with snesrecomp where the ROM and the interpreter are the ground truth: 65816 functions that can be proven safe are translated to C, and everything else runs the original ROM code in the interpreter; video, audio, and the rest of the hardware are emulated. It uses snesrev’s sm reimplementation as its symbol reference. It boots, completes the attract demo, starts a new game, goes through doors, and saves at the ship; an assisted October pass entered 255 Zebes rooms and all six Ceres rooms, collected the items, and completed the Kraid, Phantoon, and Ridley death sequences with assistance, but Mother Brain, the final escape, and the credits remain unvalidated. As optional mods it has widescreen (fit to window, 16:9, 21:9, or 32:9, with the HUD at the edges or centered) and presentation above 60 fps with interpolation, without changing game timing. Since 0.3.12 (October 17) it downloads precompiled for Windows, Linux, and macOS (Apple silicon and Intel), with nothing to build. 37 of its last 100 commits list Claude as a co-author.
