Calibration was initially frustrating, but once I got the hang of it everything worked great for PS2 Time Crisis 2 & 3, Crisis Zone, Vampire Night, & Ninja Assault...awesome!. But what about the Holy Grail of 1990's gun gaming, Virtua Cop?...it unfortunately hangs at the calibration screen as the Aimtrak documents predicts. Time for a work-around...the trick is start my FAT PS3 loading PS2 Virtua Cop Elite Edition with just a normal controller connected, select your options, then insert the Aimtrak (with both buttons pressed) when you are ready to play. This tricked my PS3 into recognising the gun ok!. Lack of calibration not a problem at this stage, perhaps because I'd got a nice calibration set-up on the previous games??. Note I also powered the Light Bar from a separate USB source as I wasn't sure if my Ps3 was providing enough juice during the initial set-ups. Anyway, this is truly awesome to finally be playing Virtua Cop 1 & 2 with a gun on an LCD TV!.
