Just to keep myself safe from blame... PLEASE DO NOT ATTEMPT THIS UNLESS YOU KNOW WHAT YOU ARE DOING I decided to just make a new thread dedicated to everything I've modified and created to have a "custom title" on sysNAND that launches redNAND It makes use of Haxchi, a DS VC exploit originally released by @smealum and then modified by @FIX94 to launch HBL and work for other games. UPDATE: The latest commit for FIX94's haxchi includes a version with cfwbooter built in, omitting the need for cfwboot.elf. Files and instructions have been updated to reflect this. Latest install.py version: 2.1.1 New in this version: Fixed bug in uploading config.txt (for some reason I made it upload to config.ini -_-) Features: Allows input of any low ID, meaning it will automatically work with future exploit games (and can possibly be used to inject DS games, untested) Makes sure the game and location provided actually exist before attempting to install Automatically downloads and modifies meta.xml with user-defined name Installs files from SD instead of uploading over network, which greatly increases speed (especially for the larger .tga meta files) As for the modified iosuhax, you will have to compile a new fw.img from the github below http://github.com/TheCyberQuake/iosuhax NEW INSTALLER AND INSTALL PROCESS: Finally got around to fixing up the installer. It's now a universal installer, and should work automatically with future exploit games. Download install.py from below, and place in the same folder as wupclient.py http://mega.nz/#!xVVAHRgL!cMJdtZD6sLp0TIQ7q6BIjNzk5xB25jr8qamy423zUoE From there you can either download a pre-made install pack from below and place it's files onto the SD card within a folder called haxchi (i.e. sd:/haxchi), or you can place any rom.zip and config.txt in /haxchi, and meta files within /haxchi/meta (excluding meta.xml, which will automatically be modified later). http://mega.nz/#F!lRFgzSJY!ANFeNyPwRM_SjlH23ca4Zg At this point I recommend grabbing the official haxchi from fix94, at least until I can rework my install packs or find a better way to do it while still being user friendly. From there you can run wupserver on the Wii U (by loading fw.img with CFW Booter or haxchi). You can then either double-click install.py, or type "python install.py" into command prompt/terminal Enter the low ID of the game you wish to install to (can be found on this github page, it's the last 8 characters of the full 16 character title ID), and then enter the games install location (USB or NAND). From there the script will install haxchi's rom.zip from sd:/haxchi, and the meta files from sd:/haxchi/meta. After that it will download meta.xml over the network to the PC, and then ask for what you wish the custom name to be (i.e. the name that shows up on home menu), then modify meta.xml to meta.xml.tmp, and then finally upload back to the Wii U. Finally, the script will attempt to install config.txt, which is needed for the latest haxchi versions made by FIX94. If it succeeds (meaning the file existed on SD) it will also apply chmod 0x644 to the file to make it properly work with haxchi.
