bsnes is an open-source Super Nintendo Entertainment System (Super Famicom) emulator. It is also available as a Libretro core for RetroArch.
bsnes is a subset project of higan, and focuses on performance, features, and ease of use. It returns to the Qt GUI that it abandoned before its merger with higan and has a much faster multi-threaded PPU renderer, giving it the performance of the old bsnes-balanced core while retaining the accuracy of the bsnes-accurate core. It was originally developed by Near (formerly known as byuu), but since his retirement in March 2020, it is now maintained by the community. It is available under the GNU GPL version 3 or later.

|PC / x86|
A newer fork of bsnes, first released in 2019 by DerKoun, that adds HD video features, such as:
- HD Mode 7 – Rendering the rotated, scaled or pseudo perspective backgrounds at higher resolutions. This does not involve new custom imagery or upscaling algorithms. It is a higher resolution version of the process the SNES uses.
- Widescreen – Extending the scenes to the left and right, without distorting them. Works for most Mode 7 scenes, but also for some other scenes/games, after some setting tweaking.
- Some non-HD related features – Like the ability to disable background layers, sprites and window effects for screenshots for wallpapers or soft crop to zoom in, leaving maps or static art off the sides of the screen.
Some of the features of this fork are or will be included in official bsnes. The difference is that official bsnes only has slight visual improvements but with mostly perfect compatibility. bsnes-hd has more hacks that give true HD in mode 7 SNES games and widescreen in other games.
Has the following improvements over regular bsnes:
- Pixel-perfect integer-ratio scaling both vertically and horizontally.
- Precise aspect ratio of 4:3 instead of 64:49 with correction enabled, in the “Center” and “Scale” modes.
- Saving screenshots in the compressed PNG format instead of uncompressed BMP.
- Drivers are not reset after crashes, a command-line option is provided for explicit reset.
- Better default settings: VSync, exclusive full-screen mode, blur disabled.
- Built-in hotkeys for full-screen and pseudo-full-screen modes, opening a game; Alt+F4 works in full-screen mode.
- Improved usability, bug fixes, and more.
This fork aims to restore functionality like HLE DSP chip emulation and SGB emulation using Gambatte that was removed in later versions of bsnes, as well as to have some optimizations that don't affect emulation accuracy. It also has an option to overclock SuperFX. Default options make it exactly the same as regular bsnes, with LLE DSP chip emulation enabled. This fork is only available as a libretro core, though it is possible to build it with Ethos (byuu's frontend) instead.
