About

A static recompilation of Super Mario Advance 2: Super Mario World for Windows that runs the original Game Boy Advance game as a native desktop application. The README labels it an experimental preview and a byproduct of developing gbarecomp, and says the v0.0.3 build boots and runs through the opening and attract sequence.

How it differs from the original

It includes an optional Adaptive Widescreen mod, disabled by default, that renders extra content at the sides instead of stretching the 240x160 image; supported gameplay scenes can expand up to 9:5.

Getting started

The README says the game ROM and GBA BIOS are not included and you must provide your own legally obtained dumps. Download the Windows zip, run SuperMarioWorldRecomp.exe and select your Super Mario Advance 2 (USA/Australia) ROM and retail GBA BIOS in the launcher, then press Play.

History

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

Known issues & limitations

This is an experimental preview, not a finished commercial port, so rough edges are expected.
The game currently boots and runs through its opening and attract sequence.
Widescreen work is still being refined scene by scene.
Some scenes keep the original view when the game does not prepare enough off-screen level or actor data.

What you need to run it
