I translated one wii game and i need create a patch, ips can't be, ppf is for playstation and use .bin files not iso.

So have any specific patch creator for wii?

ppf should still work (indeed many on the wii already did) however I will second xdelta as a general patching method (BSDiff is nice but has some potential issues with some implementations).

What I came here to say though is if you are using the original encrypted wii iso and have rebuilt it then any patch method you use will run into trouble and possibly lead to you including parts of the original iso in the patch (to say nothing of it being huge).

To this end you will probably want to use a method to inject files or get the end user to unpack the ISO, run a batch file to patch all the files you changed and rebuild it. Option 2 and possibly the better one is to make a batch file to manually extract, patch and reinsert all the files, http://gbatemp.net/topic/328729-wii-and-gc-standard-hacker-grade-iso-and-wad-manipulation-tools/ is a thread to get some tools I made although it pretty much boils down to use wit http://wit.wiimm.de/

If it is not too many files one of the translation groups way back was considering using bannerbomb (although it will probably adapt for letterbomb) to allow patching of the original disk as well but there is no simple method you can try out here that I have heard of.
