Virtua Cop - Quality of Life Improvements 1.0

Patches for Virtua Cop (Japan) on Sega Saturn that make the following changes :

• Guns can be reloaded with just a single button press on controller or mouse, as opposed to two presses normally.
• Stops the PRESS START, RANKING MODE, and GAME OVER messages from appearing during gameplay.
• Unlocks Ranking Mode: attempt to complete the game on a single credit!
• Unlocks special machine gun (set GUN SELECT to ON, pause the game, and reload six times)
• Unlocks CONTINUE -> FREE PLAY setting which grants unlimited credits.
• Unlocks six difficulty levels (Easiest / Very Easy / Medium Easy / Medium Hard / Very Hard / Hardest)
• Unlocks Option Plus menu (language can be changed from Japanese to English here)
• [OPTIONAL] Disables the white flash triggered by light guns, for the benefit of modern setups that don't require it for hit detection (e.g. MiSTer FPGA paired with GUN4IR or Sinden Lightgun)
