It will tell you SS is present but contains invalid data (or some similar wording). iXtreme checkbox will be unchecked. Its pretty obvious if you find one
There is still the possibility
that the wrong video AND pfi could be used, which wouldnt be detected (cause the app has no way of telling the original video on disc).
DMI is effectively uncheckable at the moment apart from that one string.
So pretty much you could have a perfect stealthed game with stealth files
from another ISO .
Nothing but a comparison to the actual genuine data could detect this, so the crc32 check isnt a bad idea. (Although annoying, cause .net doesnt have a native crc32 checker
)
