Hacking HD drive setup

[CORRUPT27]

Good Day,
i am totally new to hacking my WiiU and i followed the complete guide with the haxchi installed using a ds game. But my confusion is adding my Wiiu games onto a USB harddrive to play with loadline. Now i am getting mixed updates. What i understand is that loadline only works with games installed on the SD card. But to access the USB i can use Mocha CFW. This will make the WIIu think the USB hard drive is the SD card.

Since I have Haxchi installed how do I use Mocha?
Is this the best way to install games onto a USB harddrive?
Can i install anything else onto the USB harddrive such as roms for emulators and such?

I have googled like a mad man but havent really found the answer and am more confused then ever. =(

thanks for the help

Hi, you should follow this stickied guide for hacking your Wii U: https://gbatemp.net/threads/guide-community-noob-guide-to-wii-u-hacking.451297/

Now that you have Haxchi, you should take a look at session 5 of that guide, however, i'd recommend you read the entire guide, without skipping any session to make sure that you've done everything right, one simple mistake and you could potentially brick your Wii U. Good luck!
