                                  driver by   Luca Elia (l.elia@tin.it)


Two 1024x512 tilemaps. 256 color tiles. Tiles are 8x8 or a multiple (dynamic tile size).
There is RAM for 512 scroll values (line scroll). Video RAM is mirrored on multiple ranges.
One peculiarity is that video RAM access is split into high and low byte. The former is mapped
in program space, the latter in I/O space.

*SS9600

To do:

- Implement serial communication (used for protection).
- saklove, xplan: remove IRQ hacks (when an AM188-EM core will be available).
- bishjan, saklove: game is sometimes too fast (can bishjan read the VBLANK state? saklove and xplan can).
- bishjan: add sound (does it send sound commands to another device? SS9904?).
- xtrain: it runs faster than a video from the real thing. It doesn't use vblank irqs (but reads the vblank bit).
- mtrain: implement hopper. Double up does not work?
