Just sharing this project [0] I've worked on a while ago, it's not that interesting but I was proud of making it. It has a CLI and a GUI that is done with Dear ImGui and includes an instruction editor, memory and registers viewer, and a canvas that is manipulated with an extra instruction made specifically for the GUI!

This is not my first attempt at a virtual machine implementation, I've done the popular LC-3 VM before [1], check it out if you're interested to see Rust code rather than C++ ;)
