Players load cheat codes from Game Shark discs or cartridges onto the console's internal or external memory, so that when the game is loaded, the selected cheats can be applied.
When the original Game Shark was released, it came with 4,000 preloaded codes.
Codes could be entered, but unlike the Game Genie, codes were saved in the onboard flash memory and could be accessed later rather than having to be reentered.
The cartridges also acted as memory cards, with equal or greater storage capacity to the consoles' first party memory cards.
In some games, the resulting code may only work in one level or it may cause problems in other parts of the game due to memory locations being dynamically assigned.
In these cases, the user has two options: attempt to locate a pointer to the data block that their code is attempting to modify or change the game's programming which is usually located at the same place every time.
If a pointer is found, and the device supports it, a new code can be made which determines the correct location to modify from the pointer.
If the device does not support pointers the game programming must be changed instead.
During gameplay, the user presses a button on the device to open a code search menu.
Finding code is done by searching memory locations either for specific values or for values that have changed in a certain way (increased, decreased, not changed, etc.) since the last search.
After the first search, subsequent searches only look at memory locations that match the specified criteria from the last search.
Versions 3.1, 3.2 & 3.3 had a parallel port on the back, allowing the device to be connected to a PC with a program called Shark Link.
This was intended primarily to make entering a large number of codes easier but was also used for advanced hacking.
