Thank you for trying it out and for your detailed feedback!
I apologize for the confusion caused by the description. Currently, the app only supports manual step-by-step execution (using the “Load” and “STEP” buttons) for debugging the assembly code line by line.
The automatic execution / continuous RUN feature is not implemented yet in this version. However, based on your feedback, I will strongly consider adding an automatic RUN / TEST mode in a future update!
Thank you for your patience and for helping me improve the app.
