Asemu

A simple emulator in C++ built around a custom designed 24 bits cpu instruction set.

Made with the purpose of experimenting with C++, git, IDEs, build systems and coding assembly 24 bits style.

Currently you can punch hex code to boostrap your dream virtual computer or game console.

Demo is just flickering pixels by pressing arrows until screen is filled with black.

No documentation present to help.
