Go to the options menu and then try these sequences: 

up,right,down,left,up,up,left,right,left,right,down,L 
That should bring up a memory viewer. If that works, we can try what I learned on the SNES to enabled editting of the memory as well. 

up(2),down(3),right,left,right,left,down,L 
This is a remote diagnostic screen. It puts the system in a state waiting for, essentially, the server to call it. This is another way to cause updates if we get it working.
