Progress on the Arcade emulator (http://www.ppxclub.com/forum/55279-1-1).
the author will submit the driver the MAMEDev

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.
Left, center and right screens have separate programs and boards, each would work independantly, how these 3 boards communicate and coordinate is yet unknown.
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.
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. mame system21 driver does not emulate this 2D sprite layer, we have to use namcoic and namco system-II emulator instead, possibly they are not compatible with system21.
