Last post is spam... spambots are all over right now. Every forum I'm on is having a problem with them.

But it's doing surprisingly well, makes me fear that some day they'll pass the Turing test!

Who knew that when the internet would achieve sentience, it would be a spam-based lifeform? :lol:

SkyNet was born. It just play with us. Spam - his game. Soon this game bored him, and he will conquer the world! On your knees, pathetic little peoples! Behold your new owner! :3

I found some others gun which could be used...

http://www.renchi.com/renchi/AdvanceSea ... wPicture=Y

Target Box connects to anything to act like a light gun (using led bar)
=> don't know about the mode used..but it's wireless !

EMS TopGun II
=> we already talked about this one

RF TopGun
=> seems to be something like the TopGun (a clone ?)

XFPS Storm Light Gun (XCM)
=> like the others (led bar) BUT it is loaded as a keyboard + mouse on PC Side....no special driver or anything, make it "easier" to hack from the usb plug side, w/o open it


I also add Aimtrak
=> special driver, etc... Doesn't someone know what is the chip used ?

and Mag Gun
=> no led bar...wireless....EXPENSIVE! and seems to be more a joy with a shape of a "gun" that a light gun

of course, none of these helps to result the Video sync main problem but they could be seen like gun which could be hacked...
Personnaly, I'm now more into hacking the game itself ... because the video sync seems too much to handle !

Since it's a subject I'd like to see an answer, here is what I found while doing my annualy google research :

https://github.com/charcole/LCDZapper

this soon-to-be-available-on-store project uses wiimote, raspberry and video signal to activate lightgun by emiting light at the "right" moment

Here is another one

but for PC and PS1/2 only for now

This last project made me this again about using HSYNC, VSYNC and EDCLK from cart port, and so cart based only

I'm back using the first idea : make a dedicated hardware with
- video passthrough (to extract h v position with the help of a LMH1981 for ex)
- OSD to add 'something' on screen (to help auto calibration and position detection.. before that my idea needed an external gadget)
- a bluetooth receiver (to receive xy from gun device)
- a controller emulator talking to the BT receiver (so detected a menacer/justifier and toggle the TH pin at the right moment)

lol heck, I had forgotten the cartridge slot had the required signals lol

Though in either case you end up needing something going to the controller ports. I suppose that the advantage of using the cartridge slot is that then you don't need to be tapping the AV port (which is different between model 1 and 2/3 and may have been messed with during hardware mods). Also you could replace the OSD with a segment LED display on the cartridge itself instead (so you can get rid of the video passthrough for good).

If you rely on the AV port then you may need to account for the fact the output may be either composite or RGB, and that somebody may have gutted some pins to use them for S-Video instead, and again the difference between model 1 and 2…

Using a camera and a processor to track the TV as the gun shifts is a good idea, but you can't count on the output of various TVs across all games. My own thoughts on the matter was to put reflective tape on the corners of the TV, have an IR LED on the gun, and put an IR filter in front of the camera so that only reflected IR reaches the camera. Then you have four spots to define the screen. You'd tap the composite out and feed it through a sync extractor to get hsync/vsync. The control chip in the gun would turn hsync/vsync into counters to match against the gun spot derived from where the TV corners are on the camera. Then it'd assert the light gun latch line when a match occurred.

@Sik : what do you say AV is different on model 1, 2 and 3 ? If you use a composite passthrough, it will be similar to any version (and not only Genny). I'm curious....

Model 1 used a different AV jack than the later models (i.e. different shape), and you don't get the RGB signals from the cartridge slot so you need to use the ones from the AV jack, and that means having to provide a way to connect to both model 1 and model 2 style connectors (indeed this was a problem with the 32X and you needed an extra cable to connect it to a model 1 for this reason).

…or are you saying to intercept the output from the yellow RCA jack? (in which case, now you're screwing over everybody using RGB, and RGB is the most common way to connect to a modern TV through an upscaler, which would kind of defeat the whole idea)

Composhit is always available, even if one uses RGB. In a proper cable the composhit line is used for sync info for example and also acts as fallback when TV isn't supporting RGB via the SCART. It is also trivial to get luminance info out of both composhit and RGB, and sync you always have side by side anyway.
