Modding Nintendo Wii U with Homebrew and Haxchi

This is an explanation of all the steps I had to go through to make a modded Wii U in November 2018. I am not sure if it still applies, but I assume that if you have the same firmware, it should work. Basically all the info here is from wiiu.hacks.guide. The documentation can also be found on Github or as an archive per 2018.11.25. The type of Wii U used here is: Wii U with firmware 5.5.3 E. WUP-101(03) 32 GB version Reset your Wii U This whole process could take a couple of hours so make sure you have the time and patience. 🕓… Start with resetting your Wii U to factory settings. Note that you will lose all data on the Wii U if you do this. Turn on your Wii U Go to “System Settings” Go to the right until you see “Delete All Content and Settings”. Press the icon, click next, and “Delete everything”. After the formatting is complete the Wii U will shut down. Turn it back on and go through the whole “first-time-setup”. While you are at it, it is a good idea to logon with a Nintendo account, because we will need to download a game from the Wii U Store later on. You should connect to the WiFi, but try not to update the console if you are asked. Prepare the SD card and download files This information is from https://wiiu.hacks.guide/get-started Find a large SD card of at least 8 GB. Format the SD card as FAT32 and make sure it is in MBR (Master Boot Record) format. If the SD card is large, say 128 GB Windows will not format it as FAT32, but you can use the “Fat 32 Format” software tool to format it. Download the following files: […]

How to delete Steam cloud saves

Ever needed to clean up cloud saves in Steam? Unfortunately, that is not possible… However, you can intentionally corrupt the cloud save files to pretend they do not exist… 🤓 1. Get the ID of the game by finding the game on Steam store. For example the URL: http://store.steampowered.com/app/255710/Cities_Skylines/ indicates that the ID of Cities Skylines is 255710 2. Navigate to the Steam folder (not the game install folder) on your hard drive Usually under C:\. For example: C:\Program Files (x86)\Steam\userdata\YOUR_USER_ID\ 3. Use the game ID to find the folder that matches. For example C:\Program Files (x86)\Steam\userdata\106530865\255710 4. Run this PowerShell command in the “remote” folder: Note the asterisk at the end! As we cannot simply remove the files we will have to “corrupt” them, making them empty, but still present. Although there are some more steps, this did the trick for me. If it doesn’t work you might have to follow the additional steps here: https://www.youtube.com/watch?v=JADsIv2RUSw

Convert subtitles from the command line with SubtitleEdit

We can use SubtitleEdit from the command line in Windows to do batch operations on subtitle files. Just install SubtitleEdit first. If you are using the portable version, make sure you put the exe in PATH. Example: Convert TTML to SRT: It’s even easier in a Directory Opus button. Just make sure it is set to run as MS-DOS Batch function: Output: Becomes this:

Slow down video with FFmpeg

Here is a quick example on how you can use FFmpeg to slow down a video. Slowed down video by 50%: -vf setpts=2*PTS will slow down the video twice it’s original speed. -filter:a atempo=0.5 slows down the audio to 50%. Unfortunately, the caveat here is that the tempo must be in the range of 0.5 to 2.0. Also, you do not get that slow-motion down pitched sound as many slow-motion videos have.

Rotate videos with FFmpeg

There are actually two ways you can rotate videos with FFmpeg: You can rotate the video “physically” with the -vf transpose option. This will re-encode the video, thus it might degrade the video quality slightly. Or you can just change…

Convert audio to visualization video

FFmpeg has a bunch of really cool filters you can use to turn audio into visualizations. Showvolume is my favorite as it shows volume changes in real-time, but the others are great too depending on use case. avectorscope showcqt ahistogram aphasemeter showfreqs showspectrum showwaves showvolume

Merge video files together with FFmpeg

In FFmpeg merging files together is called concatenation. The video files have to have the same codec. Different file containers are allowed though. For the concatenation to work we need to make a list of every file we want to…

Merge audio and video files with FFmpeg

If the video has no audio: If the video already has audio: When you start to manipulate stuff like this you should try to get a basic grasp of FFmpeg streams. The example above is very basic so no need to dig deeper, but if you are editing a video with multiple audio tracks, for example, you should be a little careful. Here is one example if you want to know more.

Downscale video with FFMpeg

Straight to the point this time. Let’s say we want to resize an 8K video to 4K or perhaps a 4k video to HD. To downscale while keeping the aspect ratio use: To set the resolution regardless of aspect ratio…
