Wiiflow is the best thing ever! I got it fully working for both Wii and Gamecube games.
In order to use it with Nintendont, you must use the latest Wiiflow Master Mod (V4.2.3 r1053). Then in Wiiflow, you just set the source to Gamecube and it shows everything on the SD. Click on a game then click the gear icon. From here you can edit Nintendont settings such as Wiiu widescreen and NMM which is the emulated memory card. Setting it to default makes every game save to an indivisual memory card file. The last thing to do is to configure wiiflow to "Return to: Wiiflow". This way when you exit a Wii or Gamecube game, it will return to Wiiflow. But you have to install the forwarder channel first using the wiiflow channel installer.
You'll also want to configure wiiflow to show the source menu on boot. This way you can choose between Wii or Gamecube games when you first open Wiiflow.
So in the end
When starting up Wiiflow: Shows the source menu to select what type of games you want to display
When exiting a game: Goes right back to Wiiflow
Gamecube games: Wii U widescreen, single memory card per game
I absolutely love this setup, and Wiiflow works just as great as any other loader out there. I got it customized with a star night theme and music. Hands down the best loader for SD or USB on Wii U. Though I've never tested USB with it yet. I use a USB HDD for Wii U, then an SD card for vWii. Best of both worlds, don't have to unplug anything.
