Latest Release
v1.3.0 -
Added
  • Window size option.
  • Support for SSCTL audio channel register (What's Shenmue).
  • 16:9 aspect ratio for using widescreen hacks on non-16:9 monitors.
Changed
  • Introduced heuristic to detect and fix numerous issues that result in visible seams on the edges of polygons when upscaling games. These seams are commonly seen in user interfaces and most 2d games.
  • Improved handling of bad vertices that were discarded by the PowerVR (Soul Calibur intro, Mortal Kombat Gold).
  • Improved accuracy of floating-point operations, fixes numerous bugs in multiple games. Common issues were bad vertices in Soul Calibur models, bad animations in Sword of the Bersek and physics issues in Sonic Adventure - light speed dashing out of the sewer is now a breeze.
  • Refactored texture cache, improving the performance of many 2d fighters, in particular the King of Fighters series of games which really thrash the cache. On some machines, these games went from single to triple digit frame counts.
