I have a feeling you might like this: https://www.nand2tetris.org/ https://www.nand2tetris.org/ It's a popular course about building a computer from nand gates and eventually building a Tetris like game on it. All of this is done on a hardware simulator of course. If you are keen on real hardware, you might find this interesting: https://www.youtube.com/watch?v=HyznrdDSSGM&list=PLowKtXNTBypGqImE405J2565dvjafglHU https://www.youtube.com/watch?v=HyznrdDSSGM&list=PLowKtXNTBy... It's a series of videos where Ben Eater explains how to build an 8-bit computer using breadboards and basic elements of circuits. I find that his explanations are quite good as well.
