A new release of RetroCopy, a multiple systems emulator for Windows, has been released. These are the changes:
  • [EMU] Improved speed by average 20% in all cores
  • [EMU] Fixed issues with shadow/hilight mode, vertical scrolling, DMA bugs, sprite collision, aspect ratio and timing in the Genesis/Megadrive VDP
  • [EMU] Cleaned up Sega Genesis / Megadrive state, reduced size of it by 600% (allowing more rewind per megabyte)
  • [EMU] Fixed bug in 6button controller that stopped it working in some Genesis/Megadrive games [Sasha]
  • [EMU] Fixed a few Genesis/Megadrive memory map issues [Eke]
  • [EMU] Improved YM2612/Z80/VDP timing in Genesis/Megadrive (along with other fixes 98+% of all Genesis games work very good now)
  • [EMU] Fixed slowdown bug when games read input ports too much (Legend of Galahad, Kawasaki, Aleste) [Sasha]
  • [EMU] Fixed numerous bugs in YM2612 core (fixes Gynoug, Beavis and Butthead, Streets of Rage and a few other games with strange glitches) [Eke,Sasha]
  • [EMU] Cleaned up Sega Master System, Game Gear, Sega-E and Nintendo states
  • [EMU] Added "full display" option to Game Gear. Shows the full Game Gear frame which often has valid screen data.
