  Funky Jet                               (c) 1992 Data East / Mitchell Corporation
  Sotsugyo Shousho                        (c) 1995 Mitchell Corporation

  But actually a Data East pcb...  Hardware is pretty close to Super Burger
  Time but with a different graphics chip.

  Emulation by Bryan McPhail, mish@tendril.co.uk


Stephh's notes :

0) 'sotsugyo'

  - COIN2 doesn't work due to code at 0x0001f0 :

        0001F0: 1228 004A                move.b  ($4a,A0), D1

    It should be (as code in 0x00019e) :

        0001F0: 3228 004A                move.w  ($4a,A0), D1

  - SERVICE1 is very strange : instead of adding 1 credit, EACH time it is
    pressed, n credits are added depending on the "Coinage A" Dip Switch :

        Coin_A    n

         3C_1C    1
         2C_1C    1
         1C_1C    1
         1C_2C    2
         1C_3C    3
         1C_4C    4
         1C_5C    5
         1C_6C    6

  - When the "Unused" Dip Switch is ON, the palette is modified.
