N64 Gameshark Pro Manual Deblur Entry help needed

[Hoagtech]

I am trying to manually enter the Deblur Codes on my Ver 3.3 Gameshark Pro for N64.

I do not have a parallel to usb cable, And I would like to manually enter the deblur Codes according to RetroRGB's http://retrorgb.com/n64blur.html : "Remove Filters With Software"

Specifically this code for Castlevania 64:

Castlevania (USA) (Rev B):
800A28CD 0000
800A28CE 0033
800A28FD 0000
800A28FE 0033

I cannot seem to get it working or be able to end my zeros where I need to:

Is there a way to manually enter these codes?

I am getting this error message when I start the code thread.

Please help,

Is there anyone who is currently using a gamehsark to deblur?I wanted to to software deblur so I could properly review my n64 mod.

Not to be rude or anything, but reading the manual helps.

Go to select cheat codes instead of key codes.
Select your game or if it doesnt exist in the list new game.
Select new code and enter your code.
