Homebrew Problems with Ninjhax on -9U firmware > 4.5

[Myria]

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?

I think it is, yes
For me it started to fail when I downgraded my console from 9.2 to 4.5 and then created an emunand and updated it to 9.5. After that Ninjhax never worked again, even with emunand on 4.5, 7.1 and 8.1

Yes, I also had the same problem on 8.1.0-9U so I had to roll back my sysnand with a 4.5 backup and then install.

It's strange, because it works fine on 4.5.0-9U.

Yes, I also had the same problem on 8.1.0-9U so I had to roll back my sysnand with a 4.5 backup and then install.

Interesting, because that shows that this is a firmware version incompatibility issue rather than specifically a Gateway downgrade issue as previously thought.
