Last June, I brought to your attention the fan-made Fatal Frame IV translation project. The aim of the project was to do the job that Nintendo and Tecmo failed to perform by localizing the game into English. It was supposed to be completed by the end of the summer, but real-life priorities no doubt pushed back the ETA.
The best part about this patch is that it requires no modding of your Wii whatsoever! All you need is a copy of Zero: Tsukihami no Kamen, an SD card, and the patch itself. After following the instructions on the site, you should be able to run the game on any Wii regardless of region. Once activated, the patch will remain on until you manually disable it, letting you conveniently play disc at any time.
You should keep you eyes peeled on the site, though. It'll offer updates in the event that a Wii firmware update disables the patch. The team is also hard at work on extra goodies like English dubbing!
