: : What information do you need??

: : I can supply you a picture of the Sensor board, the layout of the Infrared sensors and such, I can also suppy the Sega Part #'s, however these are very expensive, remember this is a commercial system, not a home system, your looking at $500+

: Thanks,

: Any info you could provide me would be cool.

: I checked out Confidential Mission at the arcades today. It looks like they have 5 sensors at top and bottom of the screen (I am assuming these are the phototransistors because it looked like they had IR filters over them). I guess a way to be sure would be to put IR detecter paper strip up to one to be sure.

: What I am trying to do is design a similar system myself. I am currently in the process of designing a linux based arcade shooter utilizing OpenGL and either geforce3 or ATI radeon 8500 hardware. As well as it would be cool to utilize this for mame.

: I would rather use this all optical method rather than the usual screen detection method, because I would otherwise have to make a VGA pass thru system to detect the vblank and use highspeed counters for svga resolutions.

: My thoughts are that they are using 10 sensors and average them down. Probably through Op-Amps then to an ADC.

: Email me any info you can.

: Thanks,
