Answer 1

Unless the Gameshark codes.

They base on changing in-game memory.

For random example let’s say that that chunk of memory 0000FFE8 contains information about item rate drop of some monster so if you change into particullary value it will always drop item you need.

​

And the adress of memory is discovered throught analyzing the memory.

Let’s say you have 1000gold. So you’re looking for adress which cointains 00003E8. Then you’re changing in-game gold (spending or earning some) and in the adresses pool you found you’re looking for changes.
