Q11) Could I place the two LED stands behind the cloth Projector screen ?

A ) We have tried that it is workable to place the LED stands behind the cloth projector screen. But please note that our cloth projector screen may be thinner then yours. Also, the cloth screen would decrease the brightness of the infrared from the LEDs, thus the workable range for the gun should be less the normal (5m). Moreover, the life of the LEDs are limited (like normal light bulbs), it would become dimmer and dimmer (very slowly) and die finally in several years. When the LED become dimmer and dimmer and to a certain level, it would not be workable behind the cloth screen.

    could not use the gun nor enter the calibration mode in PC.


Q14) The TopGun works perfectly in PC, but I can't enter Calibration mode in PS2, what's the

        matter ?

A)  If you connect the gun to PS2 before you turn on the PS2 and it doesn't work, please re-connect

     the gun and see if it is ok.


Q15) In the calibration mode of a PS2 gun game, the PS2 fail to recognize the shoot, what's the

        matter ?

A)  It is very likely caused by bad contact. Please disconnect and re-connect the TopGun without

     reboot the PS2 console.


Q16) Would a VGA box be required for PC?

A)  No, it is not required.


Q17) Does TopGun support PS1 gun shooting games on PS2 console?

A)  Please note that you could not use any PS2 lightgun (GunCon2 compatible lightgun) to play PS1 gun

     shooting game on PS2 console. To play Area 51 on PS2 console, you have to use a PS1 compatible

     lightgun. TopGun is a GunCon2 compatible lightgun, which would not support Area 51 in PS2.

Q18) In PS2, could I use the TopGun together with PS2 joypads ?

A)  In gun shooting games, if you connect a joypad to player 1, the USB input 1 would be disabled.

     Therefore, if you are going to use the TopGun, you should not connect the joypad to PS2.

Q19) How do you recommend to fix the LED stands ?

A)  You could use BLU-TACK to fix the LED stand on the wall or besides your screen. It is some kind
