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

  The Main Event, (c) 1988 Konami
  Devastators, (c) 1988 Konami

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

Notes:
- Schematics show a palette/work RAM bank selector, but this doesn't seem
  to be used?

- In Devastators, shadows don't work. Bit 7 of the sprite attribute is always 0,
  could there be a global enable flag in the 051960?
  This is particularly evident in level 2 where plane shadows cover other sprites.
  The priority/shadow encoder PROM is quite complex, however bits 5-7 of the sprite
  attribute don't seem to be used, at least not in the first two levels, so the
  PROM just maps to the fixed priority order currently implemented.

- In Devastators, sprite zooming for the planes in level 2 is particularly bad.
