BY DEFINITION, IF YOU MAKE YOUR WII RUN A BURNED GAME, THAT'S A MOD
I didn't say anything about modding the Wii. In fact, I specifically said that the Wii wasn't touched, hence "unmodded." A burned ISO by definition can be modified. An unmodded Wii by definition cannot be modified. So when I say "how to get burned ISOs to run on unmodded Wiis," it unambiguously means, "a way to modify a burned ISO in a way that will make it able to be run on an unmodded Wii," but is just a bit more concise. As soon as you say, "make your Wii," it is clear that you did not understand the sentence. English... it's a useful thing to understand.
There is undoubtedly a way that exists, due to the nature of programming itself, to create a modified ISO that would run as a normal game would on any Wii. For some reason I strongly doubt that Nintendo did the only thing that can stop this, which is to have a copy of every Wii ISO on every Wii and have it check that the ISO on the disc is identical to the one on the Wii before allowing it to run. It's just that it could be extremely difficult if not near impossible to do. Of course this is not true if it is a physical security feature that has to do with the disc itself rather than the data on it. In that case it would be much more difficult, but still plenty possible. I don't know how the Wii detects and prevents from running unofficial ISOs on discs, and as such I can not say which case above is true, but due to the nature of programming,
if it is possible for Nintendo to make a new Wii game, it is possible for someone to make an unofficial ISO run on an unmodded Wii.
I just didn't know if people had figured out the security feature, or even if there was one, since the console was released almost 8 years ago.
