/*** DRIVER INFO **************************************************************

Grand Striker, V Goal Soccer, World Cup '94
driver by Farfetch and David Haywood

Grand Striker (c)199?  Human
V Goal Soccer (c)199?  Tecmo (2 sets)
Tecmo World Cup '94 (c) 1994 Tecmo

******************************************************************************

    Hardware notes

Both games seem to be similar hardware, V Goal Soccer doesn't work.
the hardware is also quite similar to several other Video System games.

In particular, the sound hardware is identical to aerofgt (including the
memory mapping of the Z80, it's really just a romswap), and the sprite chip
(Fujitsu CG10103) is the same used in several Video System games (see the notes
in the vidhrdw).

Grand Striker has an IRQ2 which is probably network related.

DSWs need correctly mapping, they're just commented for the moment.

TODO:
Finish hooking up the inputs
Tilemap scrolling/rotation/zooming or whatever effect it needs
Priorities are wrong. I suspect they need sprite orthogonality
Missing mixer registers (mainly layer enable/disable)
Merge with other Video System games ?

Simple protection check concept.The M68k writes a command and the MCU

The problem is that only the concept is easy,beating this protection requires a good

Misc Notes:
-Protection routine is at 0x890
-An original feature of this game is that if you enter into service mode the game gives you
the possibility to test various stuff on a pre-registered play such as the speed or
the zooming.To use it,you should use Player 2 Start button to show the test screens
