for me, ever since trucha and video mode changer, and even more so with freeloader, all games ive tried work on my PAL machine.
my suggestion is not to rely on regionfrii so much and learn to use trucha and the video mode changer, they are both somewhere in the wii hacking forum i think, it is definitely worth the effort. the success rate for me has been 100%, so i have found myself not waiting for someone to verify and go for it as soon as i see it.
sometimes a very nice person posts a ppf that patches the video modes which saves you the work... or just wait for someone to verify whether it works on PAL via regionfrii but by doing this you are really waiting at the back of the line
