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.
Not only requires emulating the game more resources, its also the configuration and imperfect N64 emulation state that muddies just a little bit. Plus a native port to PC can use everything that a normal PC game could too without tricks, such as widescreen, better controller support with new features, higher fps and so on. Emulating a game still uses the same CPU of the original system and other constraints.
