About

A static recompilation of Super Mario World (SNES) into native C using the snesrecomp framework. The 65816 CPU code is translated to C while the PPU, audio and DMA hardware are handled by a C reimplementation of the SNES hardware, and the README calls it believed fully playable.

History

The README describes the recompilation as a byproduct of developing snesrecomp, with the games as the proving ground for the framework.

Known issues & limitations

Worlds 4–7, Star Road, and Special World have not yet been hand-verified.
The widescreen mod is experimental, and the original enemy-slot pool limits how many enemies can be active in very wide views.
Widescreen is disabled in the co-op build, which always runs in standard 4:3.
Extended terrain streaming is not yet reliable during normal scrolling in the co-op build.
MSU-1 is currently disabled in the simultaneous co-op build.
During netplay, turbo, pause, and local reset are disabled.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (SNES version).

Features

Xbox, PlayStation, and Switch Pro controllers are auto-detected.
The co-op build supports two-player delay-sync netplay.

How to install

Download the Windows ZIP or Linux AppImage; extract the ZIP or make the AppImage executable.
To remap keys, edit the automatically generated `keybinds.ini` next to the executable and restart.
To play as Captain Falcon, enable the mod on the launcher's Mods page, select a Super Smash Bros. (USA) v1.0 ROM, and press Play.

Controls

Player 2 has no default keyboard bindings; configure them in `keybinds.ini` to use a second keyboard player.
Save states use Shift+F1 through Shift+F10; load states use F1 through F10; pause is P; reset is Ctrl+R; fullscreen is Alt+Enter; turbo is Tab; renderer toggle is R; and performance display is F.

Summarised from the project's README.

Status & roadmap

The README says it was hand-verified end to end through Yoshi's Island (including Iggy's castle boss) and Donut Plains, with Vanilla Dome in progress at the time of writing.
