N64 Gameshark Help

[Boyobmas]

I have a GameShark for N64 and I want to use it on my copy of Smash Bros. To access the debug menu. But it's not on the list of games on the deviceand It will only start up with games on the list (such as my Starfox 64) How would I add a game to the list? I've tried but when I take out my Starfox it feezes! Anyone done this before? Please help!
(I have a version 3.20 GameShark if that makes any difference)

This should help.

I just found that Smash Bros. actually is on the list but everytime I try to start the GS while connected to Smash it wont start up.
