spectrum screen load
Sidbox loading screen data.
Now some games hide this stuff and then run a small program to copy stuff from memory to the screen buffer.
This sidbox won't be able to do that without emulating the machine it self.
This case the system listens out for "possible" screen info on the scan part and then learns where it is.
When the bytes start to show the sidbox begins to render the screen like it would on the spectrum!
