it means that the CIA is signed in a way that it works with any console, like pre-installed games. you could say system update files are under the same definition since you can install them to any console.A legit cia is one that came from a preinstalled game on a limited edition console. I highly doubt Nintendo released a special Flashcard Timewarp console :-p
I was able to install bluecardfix to a 10.3 sysnand system seemingly without issues, though I have no cards to try it out with.That would be nice !Thanks !
since bluecardfix.cia is basically an older version of the DS card whitelist, it might cause system update notices...
