Ah, that is the missing component, Tab/Shift-tab. Thank you very much. I will google for the manual.
I tried plugging in paddles on the front of the r77, it sorta noticed them but would not move back and forth, but the fire button on player one worked I dont know if it is able too. I do not have a 2600daptor to check through USB, also I haven't tested the paddles to see if they are working fine on my 2600.
I was playing Ms. Pacman and it crashed when I died. I had to turn off the whole system.
I hope this helps....
