bsnes-hd (called ``HD Mode 7 mod, for bsnes'' in early betas) is a fork of bsnes (the great SNES emulator by Near) that adds HD video features, such as:

HD Mode 7

Renders 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

Extends the scenes to the left and right, without distorting them. It works for most Mode 7 scenes, but also for some other scenes/games, after some settings tweaking.

True color

Color calculation are done at true color instead of the SNES color depth (3x8 instead of 3x5 bit). With the optional line color smoothing color ``steps'' turn into actual gradients (without influencing the sharpness of the artwork).
