To do a ROM test or (connecting with an egg) you must:
push Reset,A,B,and C at the same time.
Let go of reset first, then the other 3 and you will be at a dark screen.
Push A,B,C,A, and the screen should say ROM TEST.
Wait and it will change to ROM OK, then push A and you will be at the Stand-By screen for connecting. Just connect like normal.
