/***************************************************************************

Big Twins
World Beach Volley
Excelsior
Hot Mind
Hard Times

driver by Nicola Salmoria and Pierpaolo Prazzoli

The games run on different, but similar, hardware. The sprite system is the
same (almost - the tile size is different).

Even if some games are from the same year, World Beach Volley is much more
advanced - more colourful, and stores setting in an EEPROM.

An interesting thing about this hardware is that the same gfx ROMs are used
to generate both 8x8 and 16x16 tiles for different tilemaps.

Hard Times and Hot Mind have different tilemaps layout than the other ones.

Hard Times was hacked from Blood Bros. program code.

Hot Mind is a romswap kit for Hard Times pcb, in fact it was found in a pcb
marked as HARD TIMES 28-06-94.


Original Bugs:
- World Beach Volley histogram functions don't work.

TODO:
- World Beach Volley sound is controlled by a pic16c57 whose ROM is missing for this game.

- One stage in Hard Times has large white blocks instead of GFX in places, are they using an
  invalid tile number that should be invisible?

- In Hard Times the last boss appears on left side of screen as it scrolls into view, are we
  missing part of the X co-ordinate?
