You can use https://dumplingapp.com/ to launch the dumpling app on your Wii U. From there, you can copy your games to a FAT32 formatted USB drive or SD card. This works for all titles except Wii VC games, which must be dumped from inside the vWii.
A full guide on this can be read at...
Possibly sometime in the future, but no one knows when. Stay on 14.4 and wait, as the lower version you're on, the more likely a jailbreak will be released for that version.
I think the only difference between 3.65 and 3.60 is that some really old homebrew won't work on 3.65.
You can't install 3.60 on some newer vitas though, so the guide now recommends 3.65.
You will need to buy a DS game from the eShop if you want your CFW to load immediately after you boot the console. If you're happy with exploiting through the browser every time you restart the console, you don't need to buy a DS game.
I just uploaded the latest version of the script now, should be compatible. Let me know on Discord if it doesn't work: Emma#1024
@Freezen99 it should work now also
