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

Various Video System Co. games using the C7-01 GGA, VS8803, VS8904, VS8905
video chips.
C7-01 GGA is used in a lot of games, some of them without sprites. So it
either controls tilemaps, or the video signal, or both.
I think 8904/8905 handle sprites, don't know about 8803.
tail2nos doesn't have the 8904/8905, and indeed it has a different sprite
system.

Driver by Nicola Salmoria


Notes:
- Sprite zoom is probably not 100% accurate.
  In pspikes, the zooming text during attract mode is horrible.

pspikes/turbofrc/aerofgtb write to two addresses which look like control
registers for a video generator. Maybe they control the display size/position.
aerofgt is different, it writes to consecutive memory addresses and the values
it writes don't seem to be related to these ones.

2007.08.25: Small note regarding DipSwitches. Locations and values have been verified for:

- svolly91 (PCB Infos from the dumper),
- aerofgt (manual),
- karatblz (US manual),
- spinlbrk (US manual),
- turbofrc (US manual)

Verification still needed for the other PCBs.

--------------------------------

This is a clone of "Power Spikes" with Italian language.
It was rather famous in Italy

--------------------------------

This bootleg is very ugly, for example it has 'bad' looking tiles
instead of the video system background on the intro screens.
This appears to be correct as the same behavior can be seen on the
real PCB and in MAME.

Sprite, and sound hardware are also modified when compared to the
original game
