Incorrect. I replaced the files and pointed a bubble to it. It did not launch unless i was in idu mode. Don't spread false information. I tested it myself. Hence why i bothered writing my steps at all.
I'm not trying to spread false information, I don't see why I would want to do that, I was just trying to help and I thank you for spending the time to write and test all of that stuff. That beign said I have a package installer on my vita installed from those same files and I can use it without entering IDU mode, I installed it long ago though so there might have been some other steps to do, but I've never even entered IDU mode once.
