Region Free Wii Games

I hacked my NTSC Wii for the purpose of playing a PAL game, I installed PriiLoader and enabled Region Free Wii Games. (for use with the disk channel) I've read this causes system instability? Is it something I should be concerned about? Is there a chance to brick my system? What's the danger. I played a few minutes of the game already and besides the aspect ratio being slightly off it seems fine.

only if you update using an out of region game. you could have bricked when you installed priiloader for that matter. to cut to the chase if the Wii works then you are fine. make sure you turn off the updates in priiloader.
