This is a Korean PC based board running Windows. The game runs fully from
the hard disk making these things rather fragile and prone to damage.
- Very little is known about the actual PC at this time, and the driver is
- just a skeleton placeholder for the CHD dump of the hard disk.

There is some other output, maybe lights?
