Well I backed up Crisis zone for my PS2 slim w/ Matrix Infinity. For some reason I can't get the game to play with the guncon 2 enabled. I can go to options and calibrate the gun fine, but it keeps forcing me to play with the controller. I'm using a matrix infinity if that matters.

Now I have tried the original and time crisis 3 backups, and both work fine with the calibration screen coming up after the game boots. What gives?
