Repairing an N64 GameShark 

Here's a "silent film" sort of deal of myself repairing an N64 GameShark.. Because it was soo spooky.
Compatibility (as taken from an official firmware update file):
Most games work immediately with the GameShark, but if your N64 cartridge will not allow you to boot up with the GameShark, you may need to change the Keycode. There are a number of different Keycodes available and this version of GameShark has the codes for the following N64 titles: Diddy Kong Racing, 1080 Snowboarding, Ken Griffey Baseball, Banjo Kazooie, Yoshi's Story. New releases may use one of the Keycodes listed above, or require a different one. If you are having trouble, please read the Keycode section on pages 7 and 8 in the GameShark Instruction Manual.
Here's a link to the official 3.2+ instruction manual:

Some GameShark versions do not support the use of keycodes. With version 3.3 you are able to change keycodes so long as you insert a game with the original lockout chip credentials (CIC-NUS-6102). This includes a lot of the original lineup such as Super Mario 64 and Mario Kart 64.
USA PAL
CIC-NUS-6102 CIC-NUS-7101 Used in 88% of games
CIC-NUS-6103 CIC-NUS-7103 Used in 3% of games (e.g 1080 Snowboarding)
CIC-NUS-6105 CIC-NUS-7105 Used in 4% of games (e.g Legend of Zelda OOT)
CIC-NUS-6106 CIC-NUS-7106 Used in 3 games (Yoshi’s Story, Cruis’n World and F-Zero X)
CIC-NUS-6101 CIC-NUS-7102 Used in 1 game: Starfox64

Special thanks to Sanni for creating the Cart Reader used in this video to reflash the GameShark. You can find more about that from his GitHub page (bit.ly/354RuoO).
A new retro buddy of mine, CheatoBaggins has also been working tirelessly on a Wiki for the N64 Gameshark which details pretty much everything you need to know about it. Check it out here:

Also here is another helpful thread he provided me with:
