World Class Bowling v1.6N [Brian Troha]
First WCB set to move the single board PCB platform. Also contains an earlier sound program.
Redumped sound 1 rom.
- Set the proper screen size.
- Decoded graphics.
- Decoded the dual-state color circuitry.
- Mapped the NVRAM, VRAM1-1, VRAM1-2, VRAM2-1 and VRAM2-2 properly.
- Emulated 2x PPI 8255 devices.
- Mapped the 4x DIP switches banks.
- Added PORT_DIPLOCATION to all DIP switches.
- Added DIP switches for 'Bet Max' and 'Limit'.
- Added DIP switches for 'Jackpot' and 'Pay Table'.
- Added the Memory Reset Switch.
- Added the 2nd video & color RAM.
- Added a 2nd tilemap for background graphics.
- Simplified the graphics banks.
- Fixed colors for foreground graphics.
- Fixed visible area to show the top of background graphics.
- Finally fixed colors for background graphics.
- Added all coinage DIP switches.
- Mapped all remaining inputs (service and player buttons).
- Added pulse time limitation to coins A, B & C.
- Switched to use 4x 8255 in replace of 2x 82c255 for I/O.
- Created a handler to feed the z80 port0 requests.
- Promoted lucky74s to 'working' state.
- Added an alternate set, but the program ROM looks like incomplete,
protected or just a bad dump.
- Parent/clone relationship.
- Added technical notes.
From Dox:
- Hooked interrupts.
- Hooked the AY8910 and therefore the NMI trigger.
- Changed the input "Key In" to active high.

Subject: An improved namcos21 driver with DRIVER'S EYES works(0125u9)
2008/06/11, by Naibo(translated to English by Mameplus team)
Driver's Eyes works,
-the communication work between CPU and 3D DSP should be limited to the master M68000,
if the address mapping is done in the shared memory, master CPU would be disturbed by the slave one.
-DIP Switches
DIP3 ON for Screen on the left
DIP4 ON for Screen on the right
should not toggle on both
-The left, center and right screens have separate programs and boards, each would work independantly.
About projection angles of left and right screen, the angle is correct on 'DRIVER'S EYES' title screen, however in the tracks of demo mode it doesn't seem correct.
-On demo screen, should fog effects be turned off?
-The game also features a pretty nice 2D sprite layer, which still doesn't show up yet.
it is known that the CPU does constantly feed the 2D video memory some meaningful and logical data.

Subject: fix for output.c unregister_client crash
My app is causing mame to crash when it unregisters itself as an output client.
Output.c's unregister_client() is guaranteed to crash because if it finds a
match then it ends up doing a "->next" twice -- once in the "if" body, and once
in the "for" statement. This patch to 0.125u8 fixes this problem. It simply adds
a "break" to the "if" body since at that point there is no need to continue.
Hope this can make it in for 0.126.
