/***************************************************************************
Dynamite Duke (c) 1989 Seibu Kaihatsu/Fabtek
The Double Dynamites (c) 1989 Seibu Kaihatsu/Fabtek
To access test mode, reset with both start buttons held.
Coins are controlled by the sound cpu, and the sound cpu is encrypted!
You need to play with sound off at the moment to coin up.
The background layer is 5bpp and I'm not 100% sure the colours are
correct on it, although the layer is 5bpp the palette data is 4bpp.
My current implementation looks pretty good though I've never seen
the real game.
There is a country code byte in the program to select between
Seibu Kaihatsu/Fabtek/Taito licenses.
