Wii U remote GDB debugging with VS Code

This guide will set up VS Code to work with debugging Wii U apps using the GDB stub plugin for Aroma.

Choosing a GDB version

To debug you will need a compatible GDB version installed which supports the powerpc:750 archtitecture.
~~The one which is bundled with devkitPPC is not recommended, due to being several versions behind.~~
Edit: It has now been updated to the latest version and can be used without issues. Use /opt/devkitpro/devkitPPC/bin/powerpc-eabi-gdb for the gdb path.
You also install a PowerPC specific version, or use gdb-multiarch which comes with several linux distributions.
Note down the path to the gdb executable, this is required for the next steps.

Install tigervnc-scraping-server

sudo apt-get install tigervnc-scraping-server

Add a password to the VNC server

vncpasswd

Today I wanted to move existing APFS-resident macOS Catalina installation to a new disk. I upgraded my late 2014 Mac Mini with a shiny new 1TB SSD. This took way too many hours of my life I will never get back. Hope this saves some time to you.

Good news:

it is possible to create a DMG image from existing APFS container with macOS Catalina installation including metadata needed for complete restore (the DMG contains OS, OS Data, Preboot, Recovery and VM volumes)
it is possible to restore this DMG image into empty APFS container and get a bootable copy of the original system

This information is relevant for Catalina (I'm currently running macOS 10.15.1).

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

	# pip3 install pyusb
	# Requires root on macOS to kick the kernel driver off the device.
