GunCon2 + ArcadeVGA

Pages: (1/4) > >>

Minwah:

I got a bit confused trying to find the answers to these questions, so if anyone knows...

Is the circuit here ( http://intruderalert.myarcade.org/GUNCON2.htm ) required for ArcadeVGA card?  I presume so but just wanted to check, since I'm not sure if the circuit is for a normal VGA card or not.

Also, from the WinGun site ( http://www.acornscity.com/guncon/index.php?language=english ), I read:

'Note: If you are shopping for a video card to use with WinGun, get a Geforce 4200 or newer Nvidia! Some Radeons have trouble with screen brightening - including the ArcadeVGA card.'

Just wondering if anyone actually has a GunCon2 working with an ArcadeVGA card?  If so, how well does it work?

Acorn:

The circuit is required for any VGA out - the input for the gun is a composite (RCA), so you must have the video stream in this format at some point in time. You can send whatever you want the the monitor (assuming it is a 15Khz monitor).

ArcadeVGA's work fine normally, to my reports. Since they use a Radeon 9200 for a base, and ATI's drivers hadn't caught up to speed by that time - you'll be missing a few features here and there, in various programs. For the guncon2 drivers this means no gamma flashing. Recently one person reported gamma flashing as working with an arcadevga, so it is possible the most recent drivers support downloadable gamma ramps (or perhaps hes using the omega hacked drivers, I don't know yet).

Minwah:

Thanks for your reply, very helpful :)

What is 'gamma flashing'?

Also, do you happen to know about the old ArcadeVGA version (based on Radeon 7000 series)?  I guess it would give similar results as you describe.

Acorn:

Gamma flashing is the screen flashing that is quoted above. Since lightguns obtain a position by reading the timing of the scanlines, and since when an area is dark/black the scanlines become invisible, lightguns cannot read a position when pointed at a dark/black area. Therefore making the entire screen bright is very helpful, since you have a chance at hitting your target *grin*. Gamma flashing is the way I came up with to brighten the screen. It does not work on older ATI cards.

The results should be similar. You can also expect some lag in HOTD2 and VirtuaCop if (and only if) you use troubleshooter with that card.

OK thanks, I knew the theory but never heard of the 'gamma' part.

So I suppose I would just have to try it and see how it goes.  I also have tinted glass which is against me...but hopefully raising the brightness should cancel that out.

I have Virtua Cop somewhere...I didn't think it ran on XP tho.  HOTD2 I'm more likely to play on Xbox (unlocked with HOTD3).  Primarily I want to use a GunCon2 gun for MAME.

Thanks again
