Walkthrough:

There are two endings.
Exit code 0 - Decline the singer's offer, or don't finish uploading and either leave or let time run out
Exit code 1 - Accept the singer's offer, finish uploading your program, and exit the interface by the specified time
Downloading the .exe and reading the memory blocks will both cause time to pass and provide additional content, but do not influence the ending you get.
