 Arcade games (hacks of console games) running on SNES harware.

TODO:

 - all games : (re)add PORT_DIPLOCATION
 - kinstb   : fix gfx glitches, missing texts
 - ffight2b : remove hack for starting credits (RAM - mainly 0x7eadce where credits are stored - is filled with 0x55,
   so you are awarded 55 credits on a hard reset)
 - sblast2b : dipswitches
 - sblast2b : pressing start during gameplay changes the character used. Intentional?
 - denseib,2: fix gfx glitches, missing texts
 - legendsb : dipswitches
 - rushbets : everything
 - venom    : gfx glitches on second level

    PQFP 100(?)pin chip marked "SP-BE0"
    PQFP 100(?)pin chip marked "SP-BH0"
    PQFP 100(?)pin chip marked "SP-AF0"
    Lattice pLSI 1024-60LJ B604S03
    6116 SRAM    x2
    AS7C256 SRAM x8
    jumper pack (12)

    two empty eprom sockets

    It's SNES version of KI with few mods (removed copyright messages,
    extra code for coin input, etc).

    256 bytes of RAM (mapped to reserved area) are shared with some
    device (probably Lattice PLD) used for handle coin inputs and dips

    Data lines of eproms are bitswapped.
