I can't get Ninjhax to work on any firmware newer than 4.5.0-9U that has a -9 browser. In other words, if you start with a 4.5.0-9U console and use a cartridge to upgrade to something newer, getting a version such as 7.2.0-9U, Ninjhax won't start. The symptoms are that Ninjhax will load the initial installer question, but when it tries to load boot.3dsx, it instead loads the Internet Browser and the Nintendo of America web site. The browser won't accept user input, so you're forced to hard power off, but it isn't frozen. Is this a known problem with Ninjhax?
