Hi guys!, I discovered some kind of debug camera in SH3 PS2 version(NTSC). You can move this camera with the PS2 controller!, so I created a few cheat codes:

**For PCSX2 .pnach cheat file**
//DEBUG CAM ON PRESS L3
patch=1,EE,D03547DC,extended,0000FFFD
patch=1,EE,21E77B30,extended,00000007

//DEBUG CAM OFF PRESS R3
patch=1,EE,D03547DC,extended,0000FFFB
patch=1,EE,21E77B30,extended,00000000

**For CodebreakerV10 or Xploder V4'**
DEBUG CAM ON PRESS L3
D03547DC 0000FFFD
21E77B30 00000007

DEBUG CAM OFF PRESS R3
D03547DC 0000FFFB
21E77B30 00000000

Usage:
D-pad up/down: cam front/back
D-pad left/right: cam left/right
L1/L2: cam up/down
Square/circle: rotation left/right
Triangle/Cross: rotation up/down

THIS DOES NOT WORK IN CUTSCENES, IF YOU PRESS L3 THE CAMERA MOVES A LITTLE BIT BUT I THINK IT IS LOCKED, IF YOU PRESS R3 THE CAMERA GOES AWAY, LOL. IF THAT HAPPENS PRESS L3 AGAIN.

I found the address for PC version. Check the pinned comment, the address is there.
