Haha, I´ve seen how PAL uses r29, but NTSC-U and NTSC-J r28.

What do you think about it? This is probably one of the very rare moments in which I´ve seen a game using different registers compared to the other region(s). I remember happening something like this on my berries code for Poképark Wii 2.

Tales of Symphonia: Dawn of the New World is the same way.  The PAL version is actually different in a few ways, it has some new items and stuffs.  It's very hard to port DotNW codes between regions because registers change, instruction order changes, and I think in some cases the way calculations are performed change as well; I was unable to port my 99.99 Grade code to PAL.

Not really new to me. Even rlwinm instructions are almost different.
