I was just getting an issue where the WAD would take too long due to a signature check and the module would fail. Download Game Nintendo Switch NSP XCI NSZ, Game Wii ISO WBFS, Game WiiU ISO Loadiine, Game 3DS CIA, Game DS Free New. I just started with an empty wii folder and did an online update. These WADs are all based on the old WADder Base WADs available through CustomizeMii and include the graphics from those channels. I have reproduced this many, many times today with the same result every time. When you are returned to the wii menu, you can no longer launch wiiware titles.
Answer 'Yes' when you get the question 'Would you like to use the Wii Shop Channel and WiiConnect24?' Click 'next' and then 'I Accept' when you see the Wii Network Services User Agreement. If you go to internet settings in the wii menu. I finally found what breaks wiiware launching. This time I tried launching a wiiware title after every step. If you do not do this, WiiGSC will throw. Install WiiGSC, then right click on it and choose Run as administrator. A WAD Manager (Wii Mod Lite is recommended). So I deleted the folder again and started over. Do NOT make a shortcut for the games Mario Party 9 or A Boy and His Blob. After importing my saves, miis and changing some settings in the wii menu, the issue was back. So today I started fresh with a new wii folder and I was able to launch wiiware games without issues.
I was always presented with the wii menu when I tried it.
I've been having issues with launching wiiware titles from my games list. If the issue is that you get the wii menu instead of launching the game, I posted this on the Dolphin forum the other day.
