@ -6,10 +6,18 @@ Spy Hunter(Tecfri bootleg)
|
||||
single PCB with 2x Z80
|
||||
|
||||
significant changes compared to original HW
|
||||
|
||||
Very different hardware, probably bootleg despite the license text printed on the PCB, similar to '1942p' and 'spartanxtec.cpp'
|
||||
PCB made by Tecfri for Recreativos Franco S.A. in Spain, has Bally Midway logo, and licensing text on the PCB.
|
||||
Board is dated '85' so seems to be a low-cost rebuild? it is unclear if it made it to market.
|
||||
|
||||
non-interlaced
|
||||
|
||||
sound system appears to be the same as 'spartanxtec.cpp'
|
||||
|
||||
how do the inputs work? is it modified to use joystick? is the sound cpu reading them / latching them via the AY?
|
||||
if so how does it communicate, timing?
