+
+Build Environment 
+
+Instructions to set it up: 
+
+Install required packages on Ubuntu 20.04 LTS WSL 2:
+sudo apt install build-essential binfmt-support daemonize libarchive-tools qemu-system qemu-user qemu-user-static gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
+
+(Download 20.04 Focal server-cloudimg-arm64-wsl.rootfs.tar.gz from Ubuntu Cloud image. Ubuntu Cloud Image)
+wget https://cloud-images.ubuntu.com/releases/focal/release/ubuntu-20.04-server-cloudimg-arm64-root.tar.xz
+
+Extract the tarball in a folder:
+
+mkdir folder
+(sudo bsdtar -xpf ubuntu-20.04-server-cloudimg-arm64-wsl.rootfs.tar.gz -C folder)
+sudo bsdtar -xpf ubuntu-20.04-server-cloudimg-arm64-root.tar.xz -C folder
+
+Copy qemu static binary into that folder:
+sudo cp /usr/bin/qemu-aarch64-static folder/usr/bin
+
+Start systemd with daemonize:
+sudo daemonize /usr/bin/unshare -fp --mount-proc /lib/systemd/systemd --system-unit=basic.target
+
+Check if AARCH64 binfmt entry is present:
+ls /proc/sys/fs/binfmt_misc/
+
+Mount and chroot into the environment:
+sudo mount -o bind /proc folder/proc
+sudo mount -o bind /dev folder/dev
+sudo chroot folder qemu-aarch64-static /bin/bash
+
+In the chroot, delete /etc/resolv.conf file and write a name server to it.
+rm /etc/resolv.conf
+echo "nameserver 8.8.8.8" > /etc/resolv.conf
+Exit chroot mkdir -p folder/tmp/.X11-unix
+
+Create chroot.sh:
+
+#!/bin/bash
+
+sudo daemonize /usr/bin/unshare -fp --mount-proc /lib/systemd/systemd --system-unit=basic.target
+
+sudo mount -o bind /proc folder/proc
+sudo mount -o bind /dev folder/dev
+sudo mount -o bind /tmp/.X11-unix folder/tmp/.X11-unix
+xhost + local:
+sudo chroot folder qemu-aarch64-static /bin/bash
+
+Make the chroot.sh executable:
+chmod +x chroot.sh
+
+Chroot into the new environment:
+sudo ./chroot.sh
+
+Update & Upgrade the chroot:
+apt-get update && apt-get upgrade 
+
+Helpful development tools & libraries to have in the chroot:
+apt-get install --no-install-recommends build-essential git wget libdrm-dev python3 python3-pip python3-setuptools python3-wheel ninja-build libopenal-dev premake4 autoconf libevdev-dev ffmpeg libboost-tools-dev magics++ libboost-thread-dev libboost-all-dev pkg-config zlib1g-dev libsdl-mixer1.2-dev libsdl1.2-dev libsdl-gfx1.2-dev libsdl2-mixer-dev clang cmake cmake-data libarchive13 libcurl4 libfreetype6-dev librhash0 libuv1 mercurial mercurial-common libgbm-dev libsdl-image1.2-dev
+
+Install custom SDL2 Libraries for better compatibility:
+rm /usr/lib/aarch64-linux-gnu/libSDL2.* 
+rm -rf /usr/lib/aarch64-linux-gnu/libSDL2-2.0.so*
+
+wget https://github.com/libsdl-org/SDL/archive/refs/tags/release-2.26.2.tar.gz
+./configure --prefix=/usr
+make -j$(nproc)
+make install
+
+/sbin/ldconfig
+
+For ScummVM build, additional packages needed
+
+apt-get install -y liba52-0.7.4-dev libjpeg62-turbo-dev libfaad-dev libsdl2-net-dev libspeechd-dev libfribidi-dev libglew-dev
