Emulating SNES games hits us right in the nostalgic feels, but playing SNES games on an 1920×1080 monitor is a painful reminder of the limitations of SNES hardware. [DerKoun] felt the same consternation, and decided to do something about it. He realized that some SNES games have much higher resolution textures that weren’t being taken advantage of. The SNES had a revolutionary video mode, mode 7, that allowed a game to set a relatively high resolution background, and then rotate and scale that background during gameplay.
This pseudo 3d effect was amazing for its time, but taking a high resolution image and squashing it into a 320 by 240 pixel viewport makes for some painful artefacts. This is where [DerKoun]’s hack comes in. He wrote a modification to the bsnes emulator, allowing those rotations and scaling to happen in full resolution, vastly improving the visuals of mode 7 games.
The latest teaser for what’s to come is shown above, mapping the mode 7 backgrounds onto a widescreen viewport, as well as HD.
Come back after the break for some mind blowing SNES HD PilotWings action!
