When creating this guide for LCD-Game-Shrinker I used the FREE Oracle VM VirtualBox with Ubuntu 20.0.4.2 LTS running under Windows 10. This is a great way to get a build environment set up quickly.
Make sure you're not using an interim release of Ubuntu as PPAs (Personal Package Archive) often lag behind new Ubuntu releases, especially interim ones like 25.04 (as of 2025-08-17).
Speaking of which, I've made a script called lcdsetup.sh
that automates upto and including Step 6 of this guide if you prefer, which you can download from my github page. download here
