AMIGA Light Guns

cebulba · 17 January 2006, 17:57

Hello folks.

Just a few questions:

1) has anybody ever tried a SEGA Light Gun on the AMIGA?

2) has anybody seen the ACTIONWARE Two-Player Light Gun interface in reality?

3) rumours told me that the ATARI XE gun works with AMIGA games. True? if so, which games?

3.a) I have two originally boxed Actionware lightguns, with the second looking exactly as the grey XE gun (only missing the ATARI XE gun logo on the side) - even the connectors are labelled ATARI. Unfortunately I didn't get it to work (maybe it's broken) with Capone. Hence this was sealed I'm sure its an original Actionware item. Any further information on that one?

4) As questioned in the marketplace thread I'm looking for a Y-Adapter Connector to connect TWO Joysticks (Light Guns) to the AMIGA Game port (Joystick Port). Can anybody provide such a cable or get me some "blue prints" on how making it myself? I have seen such a cable for ATARI and AMSTRAD computers...

about your 1)
Sega master system phaser 3050 is fully working on amiga and already tested (all my recent whdload's patches www.whdload.de support it)

but it's need a little adaptator (1 resistor+ 2 db9 femal/Male read it: http://eab.abime.net/showthread.php?t=21195/)

Sega's phaser is better than amiga phasers like Actionware/Loriciel TRojan which need a white screen flash to read coordonates of all shoots.... not the sega

(look operation wolf & operation thunderbolt whdload's patches about it http://www.whdload.de/games/OperationThunderbolt.html / http://www.whdload.de/games/OperationWolf.html)

about your 2)
I need it too to try 2 phasers support for operation thunderbolt (and in the futur Terminator 2 & cabal)

your need an adaptator (cf. my previous answer)

Chain · 18 January 2006, 12:07

no prob

thanks for info, i will build one

very strange schematics, can anyone draw it as gif or something?

It's very easy to build

1 subDB9 female (side amiga) linked by a classical 9 wires cable to 1 subDB9 male (side sega phaser)

and finally you need a little 10kOhm resistor to link pin GND and Trigger (in one of the subDB9)

it's just a pin to pin conversion with a resitor between 2 pins

I have now tested a standard Y-Adaptor cable with the ACtionware guns - but it doesn't work. Both guns are addressed as one...

Mick_AKA · 22 April 2006, 21:50

I have vague memories of my C64 light gun working on the amiga, not sure wether I still have it *runs off to route in the attic*

For the moment 2 guns are not supported because a 2 guns Actionware 's interfaces is needed to understand how gun selection works.... I am not found it for sell ...

Still looking for info on this? I bought one on ebay and it is very simple in operation. Please reply to this post if you need info on this adapter. If anyone asks, I will draw up a schematic and post it on my website.

The device works by the software setting one of the joystick pins to output mode, then toggles this pin on and off to select between the two light guns. There is a simple logic chip that chooses connects one of the light guns to the port depending on the state of the output pin. I haven't measured the frequency with which it switches between the guns, but it is quite fast. You never notice any hesitation with either gun.

I wonder if light guns will work with the Catweasel in WinUAE. If not, I should put that under req.UAE wishlist or something cause that'd be cool with my Capone game.

Well they wouldnt work on a monitor would they?

kriz · 05 October 2006, 11:44

This is for the Sega maste system lighgun ? Are there more versions than the 3050 ?

ElectroBlaster · 07 October 2006, 01:05

Anybody know if these will work, need modifying etc:

Sega CD
Konami Justifier Light Gun
Games : Lethal Enforcers, Lethal Enforcers 2, Mad Dog 2, Corpse Killer

Yes, Info still needed on that one. Can you draw a schematic?

May I see a picture of the Adapter?

let us know, please :-)

This adapter is for use with Actionware games and two Actionware compatible light guns. The games I know that accept dual gun inputs are Capone and POW.
Both are a LOT more fun with two guns >8^)

The Actionware dual gun adapter consists of five parts.
1&2) Two DB9 input connectors (I will call these Gun1_DB9 and Gun2_DB9) for plugging in the light guns.
3) A small cord with an output DB9 connector (same as the plug on the end of the cord of the gun) for plugging into the Amiga (I will call this Joy2_DB9).
4) One 74LS157 logic chip. On this particular adapter it is a Motorola chip and the full part number is SN74LS157ND, but I guess any 74LS157 would work.
5) A circuit board that connects everything.

The 74LS157 is just a "Quad 2-Line to 1-Line Data Selector/Multiplexer" (description taken right from the datasheet).
That just means that the chip can select between 2 sets of 4 bit data (on 8 input pins) that it outputs on 4 pins.
Graphically;

Case 1 - select (logic chip pin 1) low

A1
\
Y1

B1

A2
\
Y2

B2

A3
\
Y3

B3

A4
\
Y4

B4

Case 2 - select (logic chip pin 1) high

A1

Y1
/
B1

A2

Y2
/
B2

A3

Y3
/
B3

A4

Y4

B4

A truth table is a bit more concise (and I can easily include the strobe):

-------------------------------------------
|Strobe|Select|Input Ax|Input Bx|Output Yx|
-------------------------------------------
| H | X | X | X | L |
| L | L | L | X | L |
| L | L | H | X | H |
| L | H | X | L | L |
| L | H | X | H | H |
-------------------------------------------

An Actionware light gun only uses two inputs to the Amiga, so switching between the light guns only requires 2 of the 4 available selectors.
The question is this: how does the Amiga know which gun is selected and when?
There is a small trick to this. It is a little known fact (at least it was to me) that some of the joystick port pins can be set for input (normal) or output mode.
Therefore, the Actionware software sets a pin on joystick port 2 as output (in fact, it is pin 9) and actively selects which gun it wants to 'connect' to the joystick port.
I don't know how many times per second the software switches between the two guns, but if you pull the triggers on the guns at the same time, you cannot detect a difference in response time between the two.
Anyway, if you make the following connections to the chip, you should have a working Actionware two gun adapter!

logic chip pin description Signal
1 Joy2_DB9 - pin 9 Select Gun
2 Gun2_DB9 - pin 5 Fire button or sensor trigger for gun 2
3 Gun1_DB9 - pin 5 Fire button or sensor trigger for gun 1
4 Joy2_DB9 - pin 5 Fire button or sensor trigger
5 Gun2_DB9 - pin 6 Fire button or sensor trigger for gun 2
6 Gun1_DB9 - pin 6 Fire button or sensor trigger for gun 1
7 Joy2_DB9 - pin 6 Fire button or sensor trigger
8 Joy2_DB9 - pin 8 Ground (Gnd)
8 Gun2_DB9 - pin 8 Ground (Gnd)
8 Gun1_DB9 - pin 8 Ground (Gnd)
9 n/c
10 n/c
11 n/c
12 n/c
13 n/c
14 n/c
15 Joy2_DB9 - pin 8 Ground (Gnd)
16 Joy2_DB9 - pin 7 +5 Volts (+V)
16 Gun2_DB9 - pin 7 +5 Volts (+V)
16 Gun1_DB9 - pin 7 +5 Volts (+V)

I will scan the circuit board and build one of these soon to test and make sure I am don't have any mistakes in these connections. I will also draw a schematic and post these things on Aminet along with this text soon...

Drat! I forgot that this board deletes extra spaces. The aminet file will be up soon.
