additional information
info 0.37b13 [David Haywood, Nicola Salmoria]

TODO:
  • Accurate sound
TEST MODE:
  • Press Player 2 buttons 1+2 during reset. "Ready?" will appear. Then press Player 2 button 1 three times.
WIP:
  • 0.125u4: Nicola Salmoria optimised tilemap_draw rowscroll case to avoid overhead when used with clip rects smaller than the tilemap. This reduces by an order of magnitude the time taken to render the background in Gunnail stage 5. This fixed also the gfx mess after you kill a boss. Changed 68000 clock speed to 12MHz.
  • 0.106u3: Changed 'Unknown' dipswitches to 'Unused'.
  • 0.94u2: Added YM2203 (1.5MHz) sound and swapped sound1/2 roms. Added dipswitches 'Language', 'Difficulty' and 'Demo Sounds'.
  • 2nd January 2002: David Haywood fixed the bad sprites in Gunnail.
  • 25th May 2001: David Haywood re-submitted a fix to Gunnail crash.
  • 15th May 2001: Guru - Purchased Gun Nail from a PCB shop in Japan with the help of Team Japump in February.
  • 26th April 2001: David Haywood fixed Gunnail from crashing in the Win32 version.
  • 0.37b14: Added 'Coin A/B' dipswitches.
  • 16th March 2001: Brad Oliver fixed some crash-causing bugs in the Gunnail driver. Marco Cassili fixed dip switch settings in Gunnail.
  • 0.37b13: David Haywood added GunNail (NMK/Tecmo 1993).
  • 1st March 2001: David Haywood and Nicola Salmoria added Gunnail to the Bombjack Twin driver.
