MGS: Twin Snakes 60hz option?

[lostn]

Namco were hit and miss after Klonoa 2 afaik Time Crisis 2 didn't have 60hz either.

Could that have something to do with the guns only working accurately at 50hz? I know for sure they don't work on 100hz TVs...

Capcom's gun games (Dino Stalker and RE: Dead Aim) both work fine at 60hz.

Sorry to butt in, but for those who expressed an interest in getting the NTSC version of this, I have US MGS: Twin Snakes available for sale in the sales thread .

PM me if you're interested. Cheers.

P.S. Awsome, awsome game. My first MGS experience on any format and it blew me away. I'm about to get Substance and going to pre-order SE. A shame it'll be the last ... now, how about they go and make a Snake movie ....

i actually suffer from this in my house

its nothing to do with 50/60hz its definately 100hz

both my tv's are 100hz and the one in my bedroom doesnt have an off switch so i'm stuck

from what i know its something to do with 100hz consistantly doing a sweeping scan of the screen so the picture is always updated, so when you shoot on the light gun it wont appear in the place you shot

i even tried this about an inch away from the screen and it appeared on the other side of the screen

most televisions nowadays allow you to switch this option off

So the video game console will actually be running in 100hz instead of 50hz? I didn't think the consoles themselves supported that refresh rate...

What happens if you're running an NTSC game? Will it be 120hz?

Lightguns work by using the screen's sync for positioning, if the gun is designed for a certain refresh rate (50/60hz) it wont work correctly at a different rate - it's nothing to do with a console running at 100hz.

Light guns rely on the screen redrawing in a particular way. For ones designed to work with TVs, that's a 50/60Hz interlaced display. When the game system knows how the screen's being redrawn, it knows what's appearing on the screen at any moment; your high-persistence eyes can't see the fast-moving electron beam dot painting the screen over and over, but the low-persistence sensor in the light gun can. When the light gun's lens is pointed at the dot, the game system knows where it's aimed. Simpler light gun systems only track the aim when you fire (the whole screen, or the target, flash white then, and that's when the gun's aim is computed); fancier ones can track all the time, and thus display a crosshair.

LCD and plasma screen monitors or TVs don't have a scanning dot at all; neither do non-CRT projectors. De-interlaced CRT TVs that run at 100Hz or higher refresh rates do have a scanning dot, but it scans faster than the game system expects, because each of the interlaced fields of the image is doubled up into a whole frame, to create the low-flicker doubled refresh rate. This messes up the light gun tracking, too.

Conventional light guns will never work with non-CRT displays, but ones with cameras or otherwise improved position tracking could. Making them work with 100Hz CRT TVs is a lot simpler, but I don't think anybody's actually done it yet.
