SM 0 a9f4 writes a9 f4 into memory at address 0
G 0 starts executing at address 0
A9F4 is the ExitToShell A-trap, which terminates the
current process. Looks like AtEase was rather easy to
bypass -- all you had to do was kill it!
Nobody's tried to claim their virtual chocolate fish yet,
btw. If you want a clue, the CPU was a National SC/MP...
