About a year ago, I put together a visual emulator based on the Simple-As-Possible architecture, tossed it on GitHub, and kind of forgot about it. While digging through some old projects, I came across it and decided to upload it here!

What can you do with it?

• Enter Assembly instructions and manipulate memory values by entering instructions on the keypad interface. 
• Run simple programs to add, subtract, and display results. 
• Step through programs to watch how the registers behave at each step.
• Save/Load programs 1-4, externally edit source and RAM files in the src directory and run them in the game.
