I'm having the same problem as many others here, I install the new source, and there is not a new folder appearing. I've restarted my springboard, checked the sources over, deleted and re-added the source, and still nothing. Does the server being down have something to do with the lack of a folder being made?
Sorry if I'm making this harder than normal. I don't see how I can manually add my own Roms, but doing it automatically makes me confused, lmao.
