/*** 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)
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 ?
