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.
