How to play Pokemon Stadium 2 on the N64 Gameshark. With Codes!

Here's a tutorial on how to use the Gameshark with PKS2 for the N64. I highly recommend watching the whole. Its long but there is some stuff at the end that you need to know (since I forgot all about it until the last second).
If you didn't watch the whole video, make sure to watch at 23:20 for instructions on what to do after the N64 is turned off.
