On November 5, developer Darhkfox released an unofficial free PC port of Super Mario All-Stars. The project has since been updated to version 1.1.1, offering builds for Steam Deck, Linux, and Android. This port adds features such as widescreen display, two-player co-op across three titles, and 82 achievements.
The original Super Mario All-Stars was released for the SNES in 1993, featuring 16-bit remakes of Super Mario Bros., Super Mario Bros. 2, Super Mario Bros. 3, and Super Mario Bros.: The Lost Levels. The unofficial port does not include any Nintendo game files; users must provide their own compatible North American ROM, which the developer requests be extracted from an original cartridge.
The widescreen mode does not simply stretch the image; instead, it expands the actual visible area and readjusts UI positioning, with options for 16:9, 16:10, or 21:9 aspect ratios. Super Mario Bros., Super Mario Bros.: The Lost Levels, and Super Mario Bros. 3 also support simultaneous play as Mario and Luigi, changing the original turn-based gameplay into two-player co-op.
Other features include instant save states, rewind, fast forward, level selection, cheat options, CRT effects, alternative color palettes, and a built-in music player. The 1.1 update added custom soundtracks, launcher themes, and version notifications. This project is not affiliated with or endorsed by Nintendo, and it remains uncertain how long its code repository will remain available.
