HD Mode 7 mod is a mod of bsnes by byuu (high-level emulation for co-processors came right on time for this). It performs Mode 7 transformations (incl. HDMA) at up to 4 times the horizontal and vertical resolution.
Zitat:
New in this version:
Widescreen: Setting to expand Mode 7 backgrounds to the left and right for a 16:9 aspect ratio.
Tweaked the behavior of Output/Center to drop the top and bottom 4 scanlines in 1080p fullscreen. This bumps the scaling form 4x to 5x and with widescreen allows native 1080p fullscreen Mode 7 with uniformly scaled sprites.
Replaced magic numbers with preliminary detection for values at the edges that break perspective correction. Fixes Tales of Phantasia (and should not break Super Mario Kart).
Disabled the automatic switching to non-scaled when there is no Mode 7 background, as it breaks with widescreen. [may also help with some shaders, IIRC someone asked for this]
