• Significant performance improvement / reduced CPU usage due to a rewrite of the 6502 CPU emulation code
• Fixed a PPU bug where the PPU would sometimes render the wrong backdrop color when rendering was left disabled at the start of a frame; this caused occasional top-of-screen flickering in Battletoads, which leaves rendering disabled for the first ~7 visible scanlines of every frame
• Fixed a bug that caused PAL audio sync to time to ~49.9 FPS instead of 50 FPS
• Added an option to have audio sync time to native NES speed (~60.1 FPS NTSC / ~50.007 FPS PAL) instead of aiming for exactly 60 FPS NTSC / 50 FPS PAL
  • Note this will cause severe audio skipping if combined with VSync on a display with 60Hz refresh rate
