I just tested pcsx2. I feel a bit dumb, last time I tested I forgot to disable the widescreen hacks, reason why it wasn't aiming properly. Without it it's working perfectly ::)
Still looking for a way to play those games correctly in 16/9 tho, it would look great.

Hey JayBee

What problem are you having with 16:9?
You can set the aspect ratio in the be window settings.
You can also set the window size.
I haven’t found it necessary but you can also set a custom internal resolution in the video plugin settings.

Just setting the 16:9 aspect ratio works for me though.

If you are having trouble where the aim is fine in the Center but drifts off on one or more axis as you go towards the edge then you need to tweak the 4 values in the gun on profiles for the game that you are using to get the aim consistent for your screen set up.

Which game are you trying?

Samco - I meant to say that I got all of the parts and managed to build a copy of your gun.

Its almost working but I've obviously done something wrong as the camera doesn't seem to get consistent power. I think I haven't soldered it very well (Its the first time that I have soldered anything in years!)

It works for a few seconds but then when it temporarily loses power to the camera (the red camera light flickers) the whole thing stops working. Would that be the behavior you would expect if it was losing power to the camera?

You're right, I didn't touch the settings of the plug-in yet, I wanted to see how it was working without changing anything.
The issue I get in pcsx2 is that when I use the widescreen hacks and 16:9 ratio for timecrisis 3 (I must admit it's the only ps2 lightgun game I tested so far), even if the game is displayed well in full 16:9, the lightgun is still registered only in the 4:3 zone of the screen, as it was intended in the original game.
So the aiming is perfect, but I can't shoot on the left and right borders ::)
Back with native 4:3 it works perfectly.
I will follow your advice and try to change the settings to see if I can make the aiming fit the 16:9 aspect.

For your camera issue, I would check the soldering first, to see if you have no short circuit or bad connection, the led of the camera should be either always on when it's working, or always off. Do you have a multimeter or a continuity tester that you can use?

lightgungamer:
I’ve definitely had that same problem before but I can’t remember how I fixed it. I might have just deleted my install and started fresh.

I’ve just tried it with and without the full screen hacks and it doesn’t seem to make any difference. It works both ways for me.

I would check internal and window resolution and make sure they are both at least in a 16:9 ratio.

Re the camera - I think you are right. I don’t have a multimeter but I’m planning on getting one so I can check. I think that must be it because if I press it at an angle then it seems to fix the connection. I can’t see anything wrong visually though.

samco:
Hi Lightgungamer,

Yeah, from your description (especially the part about pressing on it fixes it) it sounds like it probably is a soldering issue. Because your getting power intermittently it must be close to connection thou, maybe try reheating your soldering points. Power is supplied to the camera from pin "5" in my sketch so maybe start with that.
