well im JUST starting on my first mame project.. and have no intent on putting any guns no it because of it's style 45degree slanted monitor.
with that said i DO very much want to also do a gun cabinet, like t2 with the positional guns, those could be used for any gun game, but it would'nt be authentic on light gun games, so i'd probably make a mostly blank CP for light guns on that type of cabinet.
with that in mind i'd say 2 feet would be cutting it close.. i'd say 1 foot or 1//2 foot on a 19inch.. 2 feet should be ok for a 25inch.
max range you'ed probably use them would be say 5-6 feet.
i know a lot of people are going for LCD but if it worked with crt and lcd i think that would be great.
as others said the namco and sega guns are both nice designs.. i know recoil really is a nice touch mabe 2 version one with and without recoil.. and i also agree build qualty should be high, thick plastic is a must.
a 100 bucks for a high quality gun with recoil i think would be a great deal
preferrably in black or black/chrome as a glock/45/Desert Eagle. Please no lime green or oinge
Thats another issue. I think in most jurisdictions the gun would need to be a "non-gun" color otherwise it would be illegal to sell it as it would be a replica gun. Thats why the gaming guns are these colors.
in the states toy guns have to have a bright orange tip.. the gun it self can look as real as you want it to be (check out air soft guns), but it has to have a orange tip.. alternatively you can make the whole gun bright red or orange or yellow or what ever if you wanted.
it's also illegal to remove the orange tip.
now.. with that said im not sure if that would apply to arcade guns with a cord attached.
in any event you could make the tip snap on.. rather then glued on.. and any one who removes it can do so without destorying the gun but also takes the reasponsability of it.
after all you complied within the law.
or probably an easier was to get around it would be to make the gun gun clear, or white plastic.. or at least offer it in these one of these 2 choices.
you can die plastic easily enough, as long as it's a lighter color then what you're making it.
IE: you can't die black something else.. but white can turn into anything.
and dying plastic is a lot better result then spray painting it.
now as far as gun styles my votes for a beretta 92, which i consider one of the sexiest guns of all time.
