A new PC port of Super Mario 64, with native Linux version. It comes as an AppImage, and requires a ROM file of the original game.
Seems to work well. FPS is locked to 30 by default, but you can change that from the settings. It even supports ultrawide resolutions, with the possibility to change HUD aspect ratio to 16:9.
It also supports HD texture packs, such as this one: https://github.com/GhostlyDark/SM64-Reloaded-GS. Just decompress it in to the mods folder, and toggle between original and alternative textures with the Tab key.
I actually followed some devlogs for this, and nobody knows who owns the rights to that game anymore. The original developing company was bought out, then merged, then bought out again, then the rights sold off in a bundled deal, and whatever else. They can’t figure out the legal shit for that project, and no company knows if they own the rights to even sue over.
