King of Boxer - (c) 1985 Woodplace Inc.
Ring King - (c) 1985 Data East USA Inc.
Preliminary driver by:
Ernesto Corvi
ernesto@imagina.com
Notes:
-----
Main CPU:
- Theres a memory area from 0xf000 to 0xf7ff, wich is clearly
initialized at startup and never used anymore.
Ring King specific:
- Colors for some boxers are wrong.
