Hardware AnyRegion Changer - Video Modes

[broacrazy]

I have a 4.0J wii. For some reason, my NTSC-U black ops only works when I force the video mode to PAL60. If I use AnyRegion Changer and set the video mode to PAL, and leave everything else untouched, will it be safe? More importantly, can my black ops run in colour after the switch? I tried forcing the video mode to PAL50, and black ops still runs in black and white, and PAL60 is the same thing. I mainly use PAL60 since it feels smoother. It's just that everything is in black and white. Please help...
