The microcontroller determines the position based on the posisition of the web-cammed dots or the seen screen rectangle, and turns it into a mouse coordinate as if it was a 1:1 tablet-screen device.

I totally agree. This would be an improvement over the Wii-mote as it would add accuracy by having dots at each corner.
I looked at this possibility a while back but could not find a camera module which outputs separate H and V sync. They are all composite video. This would mean a sync separator and delays etc affecting the accuracy. There are "bare" camera chips which send separate sync but then it would need a lens assembly etc.
A microcontroller alone would not be fast enough to count the H sync pulses or do the timing, but it could be done using external circuitry. The best method of all would be a custom image chip, with everything on-board. This is perfectly possible technically (as the Wii shows) but not sure if practical in relatively low volumes. I will try to find out though.

It's like shooting on a fancy fair with way too many beers in your body. Nothing compared to the old NES Zapper, which was dead-accurate (and used the black screen with white-box method).

No I haven't tried it. I have tried a Gyration Gryotransport and it works as a mouse as intended, but is useless as a 'gun'.
I'm still looking for the article on the Guncon 3 that comes with Time Crisis 4. Whether it really is using Wii mote technology or not, it is a pretty nice gun as far as responsiveness and accuracy. If the Wii mote is out, then the Guncon 3 should be looked at as far as getting a PC driver going.

People can check their computers. A lot (not all) newer PCs already have Bluetooth. I have a Bluetooth adapter already, so in my case that's a none factor. $30 is too much for one, they can be had for much cheaper than that, I'd look around if that's the price you see.
The Wii mote... yeah $40 retail. Then you have to buy the 'gun' for another $15-$20. Sensor bars can be bought or made. GameStop usually sells used gear. It depends on your area though I guess. In my area a used Wii mote is $34. Down in PA my son can get a used one for $20. I know myself and others would feel better about tearing apart a $20 used one than a $40 new one.
Here are some camera based guns like you guys were mentioning...
I'm not sure if this one works with a PC

This works with a PC and is supposed to be the most accurate (but also the most expensive) and uses the same technology developed by the military and used by them and police forces for training. It also is camera based.

I'm not even sure how well it would work with a CRT monitor since it is designed to be used with a projector. It's really a moot point though because at $2000 I doubt anyone is going to be running out to buy one for an arcade.
Here are my thoughts though. We know the Guncon 2 works, and so does the Topgun when you get it setup. I'm reading of success reports with the Wii mote, including using two of them- but I also hear some people say they aren't very accurate, yet others say they are. Then again, I hear the same thing about the Topgun's.
My thoughts are that we have guns already so I am one that likes keeping things as simple as possible. I don't know if changing code in MAME is an answer. That could cause other things that currently work to blow up until all the bugs are worked out. We know certain things work and certain things don't... and then there are the items that are questionable, mainly because there are no drivers for them. Drivers and existing guns seems like the best approach in my opinion.

man you ever look back on one of your posts and realized that you seemed like you were drunk. anyways no new news yet. like i said i have been playing around with the wii mote, buti really am starting to dislike it. i guess i coderight some code to improve the functionality of it. the problem with the wii mote is that it needs a script that not only will get the aim right but adjust that aim the further you get from the screen,but like i said i am realy not happy with it at the moment .I am just hoping that hagstom can build this interface.
Paul Olson:
$150 is certainly on the high end of what I would pay, but if all of the gun games played arcade accurate, I think I would buy it.

no reply yet probably here back from them after the holidays if not i e-mail them back
