Hi, I have the same issue.
The earlier test version was giving me the stable message. I checked date and time and these were ok (or need the date and time be in a certain range?).
Then I checked the github and saw the new release of 4 hours ago, and installed that one. Now I see the colored bars as well. However I hear the music of the menu I configured, so apart from the screen it seems to get into USB Loader GX again.
I was having a similar issue, I just updated and got a black screen when booting a GameCube game but the audio was working, pressed the home button to go back to USB Loader but the screen remained black. I turned off the console, loaded USB Loader again, and went to Loader settings, the video mode for Nintendont was set to Auto, I changed it to System default and now the game boots like normal, but then I tried setting it back to Auto and it still works, so there's either some sort of issue with the video mode settings or with the Loader itself when booting for the first time. In any case my issue seems to be fixed.
I'm using a Wii U with an HDMI cable.






. I downloaded the stable version that was just uploaded today on the github. What I did was delete the usbloadergx folder in the app directory and replaced it with the new one from this github. Now when I load usbloadergx, I get an exception. Are there additional steps to doing the install?
