GunCon2 on PC-monitor
Lilwolf:
btw, does it seem like it will always need a jpac?

I would love the get a set of these, but don't know if its possible.
btw, anyone try outputting to both VGA and TV-OUT at the same time and then use the composite out for sync? or is that just a pipedream?

I'm trying this now with the guncons I just received; so far, no dice.
I've verified the "cloned" desktop on a 13" TV via s-video to composite converter.
The gun IS recognized by the driver when pointed at the Wells Gardner D9200.
However, I can't calibrate it correctly.
The cursor "responds" to movement of the gun, but it's jumpy (all over the place).\
If I point the gun at the 13" TV when calibrating, it calibrates correctly.
I can only (so far) hypothesize that there is some difference / delay between the s-video output syncs and the VGA syncs feeding the D9200.
Any help / advice appreciated.

Lilwolf:
COOL! So you are working a solution that will work without a jpac!
I wasn't sure if the only work was being done requiring a jpac.

Hi,
Sorry for general lack of info - not been around much since. When I posted that I thought I had to use interlace modes - although since I've had success in just plain old progressive. I've had a catalogue of minor errors on this such as one of my 2 guns not working at all - but me assuming it just wasn't working with my setup, it also appears that being 100Hz gun, the scorpion may well have 2 "modes" to cater for progressive output - what and how to switch the modes I have no idea - presumably 1st thing its pointed at, but fiddly when you are testing with powerstrip. I was also not terminating the sync signal correctly (it appears the composite connector on the gun does not terminate the signal - this is perhaps obvious as its a pass through, but I'm still surprised).
I havn't actually got it hooked up to a TV yet so can't compare accuracy. It gets slightly less accurate as you increase resolution (ie smallest hop in 1024x768i was around "5" units directly reported by the gun, moves down to 2/3 at 800x600. Still playable with though.
Anyway, i don't actually own a jpac - I was just provided with the chip off it that converts vga syncs to composite for testing. As the Jpac is quite pricey for this, and it looks like zeropoints got a working circuit from the ground up it may well be best/cheaper to see what he comes up with. I'll try and post a wiring diagram tomorrow for the chip.
I don't think I'm going to get much time to play with this again till next week - I'd like to test more to sort out what progressive resolutions are ok and if the gun really is changing modes at all....
