games are locked to certain regions and only some games in pal play in 60hz most play in 50hz so you'll get a black screen or black and white if you use the region free settings and mess with the video patching settings you might be able to get it to boot.
For example I had this same problem with DBZ BT3 pal version it only displays in 50hz once I change a few video settings forced ntsc video with all video patching it booted properly also don't forget to install priiloader and turn on the region free system menu hacks to use region free settings on your whole system instead of a single software
