Knuckle Joe - (c) 1985 Seibu Kaihatsu ( Taito License )

driver by Ernesto Corvi

Notes:
This board seems to be an Irem design.
The sound hardware is definitely the 6803-based one used by the classic Irem
games, and the video hardware is pretty much like Irem games too. The only
strange thing is that the screen is flipped vertically.

TODO:
- sprite vs. sprite priority especially on ground level

Updates:
- you can't play anymore after you die(clock speed too low, check XTAL)
- scrolling in bike levels(scroll register overflow)
- sprites disappearing at left screen edge(bad clipping)
- artifacts in stage 3 and others(clear sprite mem at bank switch?)
