Mega Man Zero

Game Boy Advance · 2026

The famously cramped Mega Man Zero games, given room to breathe with opt-in fixed-width or adaptive widescreen.

The Mega Man Zero games are notoriously cramped by the GBA's 3:2 screen, and the collection re-releases never addressed it. This GBARecomp project takes that problem on directly. It is the consumer repository for the Zero series, with support arriving across the games, currently at v0.0.3 (2026-07-17).

What works today

The game runs through the recompiled runtime as an experimental preview, the honest label the framework applies to its whole lineup.

Enhancements

Native 3:2 presentation plus opt-in widescreen with a choice of policies via --resize-view: fixed-width, or adaptive, which follows the window shape. For a series where screen real estate is the classic complaint, a wider logical view is the headline feature.

Known limitations

Save states and widescreen have a known interaction issue.

No game data is distributed; the project builds from your own legally dumped ROM and GBA BIOS.
