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.
