This is an SMS with a timer system, official Sega product. Cabinet has a lightgun, it runs the SMS light gun games.
|
||||
|
||||
It has 2 IO controllers, and 1 VDP, so I'm guessing the BIOS just displays to some kind of Segment LED display.

Notes:
|
||||
(1) apparently.... seems a bit odd, because it's not a gun game
|
||||
(2) an auction has been observed with Out Run instead of this
|
||||
Apparently the first revision only had a gun, the second (the one dumped) had both a gun and a joystick.
|
||||
Multiple auctions and pics on the web show different cartridge configurations, so the driver lets you select the whole SMS library.
|
||||
To try the selection listed above use the following command:
|
||||
mame shtzone -cart1 blackblt -cart2 shooting -cart3 gangster -cart4 marksman -cart5 fantzone
|
||||
|
||||
Stuck at 'set cartridge', currently only the VDP and basic inputs for the timer CPU are hooked up.
|
||||
It's possible to enter test mode.
|
||||
|
||||
TODO:
|
||||
- hook up SMS CPU and carts reading, SMS-side inputs;
|
||||
- outputs (test mode lists LED lamp, gun solenoid and buzzer);
|
||||
- very similar to smssdisp in sms.cpp, merge?
|
||||
- gun?
|
||||
- actual timer doesn't seem to match what's set by the dips. Communications problem?
|
||||
- outputs (test mode lists LED lamp, gun solenoid and buzzer). Lamp is done, buzzer maybe, gun solenoid isn't.
|
||||
- the driver currently assumes the buzzer is used to acknowledge when a coin is inserted.
|
||||
- should also have 1 card slot according to forum posts.
|
||||
- layout for the led.
