I don't like hanging IR transmitters all over my TV, though. And the ones TC4 comes with are FUGLY!
I put clear stickers with anime chicks on them. They still work.
It does suck you cant use the PS3 gun for PS1 games. Definitely made me angry.
...and, I do think it works better than the Wii alot of the time.
note: you can use the wii sensor bar for the PS3 lightgun. It just requires you to have your wii on at the same time, lol
...you can also use two hot candles. or anything hot.
