  GOINDOL

  Driver provided by Jarek Parchanski (jpdev@friko6.onet.pl)

Notes:
- byte at 7f87 controls region:
  0 = Japan
  1 = USA
  2 = World
  Regardless of the setting of this byte, the startup notice in Korean is
  always displayed.
  After the title screen, depending on the byte you get "for use only in Japan",
  "for use only in USA", or the Korean notice again! So 2 might actually mean
  Korea instead of World... but that version surely got to Europe since Gerald
  has three boards with this ROM.
