|

PCB is marked 'Ver 1.8 B/D-' on 2 of the edges
|
||||
|
||||
Custom chip marked
|
||||
ORIENTAL SOFT
|
||||
SPR800F1
|
||||

|
||||
|
||||
inputs need finishing off
|
||||
|
||||
-- Test Mode Note --
|
||||
|
||||
The test mode for this game is very buggy, this is not a MAME bug
|
||||
the same behavior has been observed on the original PCB.
|
||||
|
||||
One example of this is the dipswitch viewer, which should show 3
|
||||
rows of 8 1/0 values, one for each switch. ie
|
||||
|
||||
00000000
|
||||
00000000
|
||||
00000000
|
||||
|
||||
However..
|
||||
|
||||
Instead of properly representing each of the dips, the 1st switch in
|
||||
each bank ends up turning on/off the entire row display (for rows 2/3
|
||||
it shifts row 1 by one pixel)
|
||||
|
||||
This then means the 2nd switch changes the digit in the 1st position
|
||||
so
|
||||
|
||||
10000000
|
||||
|
||||
the 8th switch changes the 7th digit so
|
||||
|
||||
10000010
|
||||
|
||||
and there's no way at all to change the last digit.
