I know similar questions have been asked quite a few times, but I've done a lot of digging through loads of topics, and I am STILL kinda confused. I'm interested in installing games on my NAND/USB. The last method I had contact with was the wup installer for which you needed to have tickets, which, from what I remember, came only with games which had their physical releases. The thing is that I'd like to install games which appeared only in eshop and have never been released on a DVD e.g. pictoparty. I might be also interested in installation of different region games.
Which option should I go for: Mocha or Haxchi?

 

In other words - if I buy a DS game I'll have the opportunity to play offline, but if the scrooge nature of myself comes out and I decide to go for Mocha, I'll have to have Internet connection to play games? Apart from that they are an exact same thing? What in terms of stability?

 

They are both 100% stable just with Mocha like I said each time you boot the wiiu you need internet access so as to be able to load mocha

 

Try NUSPacker:

You can install/run out-of-region titles after executing Haxchi's sysmenu option (or Mocha), so for Tumblestone specifically, just load the US version.

 

Does Haxchi automatically kick you out right back to the system menu? If not then you are not entering into a CFW. If you click Haxchi and it takes you to the HBL(HomeBrew Loader) then this is your problem. Simply using Haxchi to boot into HBL does not launch a CFW. If you did not touch your config file then it auto boots HBL and NOT CFW. Hold down b while launching Haxchi, this should kick you back to system menu, you are now in CFW. You can verify by going into settings and looking at your version number, it should say 99.99.99 when you are in Haxchi's CFW.
