Update Notes:

V4:
So this is the 4th iteration of my CPU lol... I added a few programs for you all to try out and you can even use an assembler now!

V5:
Long time since I updated this... But I've added a GPU! It's called "Color burst" and you can go try out some premade programs I have added on it! There's an assembler guide with GPU dev guide and I encourage you all to go try and make some graphical programs! Also more docs can be found on it's project page.

To-Do:
Increase amount of registers to 8
Make a simple command line
Make a simple operating system for the CPU
