Not sure what mod is on my Wii U

[CallMe_David]

I haven't touched my Wii U in probably a couple of years, and I'm wanting to install Aroma on it.  I know I modded the Wii U a long time ago, but I'm not sure what mod I used.  I'd like to just factory reset the console and start from scratch with Aroma.  Even if a wipe is not needed, it's still what I'd prefer to do.

 

There are games installed to it that are defiantly pirated and playable, so I know there's still a mod applied to the system.

When I launch "Health and Safety," I get a black screen on the tv and gamepad saying, "Don't run the EnvironmentLoader twice.  If you want to open the Homebrew Launcher, launch the Mii Maker instead."

 

When I launch "Mii Maker," I get the Homebrew Channel v1.5, and in the list I have:

HB App Store
Bloopair Pairing Menu
SaveMii
UFDiine
wudd.rpx
WUP Installer GX2

 

I've also attached the contents of the root directory of the SD card in the system, and there is also a Nintendo ID tied to the system (got the orange N over my avatar).
