Memory address

A memory address, or address is the location of an x-bit, although normally an 8-bit byte denoted in the hexadecimal notation of Z(x)XXYY. For example, in Pokémon Red and Blue the species of a forced Pokémon encounter is defined by the identifier of the memory address 0xD059.

Cheating devices such as the GameShark however, often refer to a memory-address in little-endian notation hence in this case, the GameShark code to instantly encounter a given Pokémon would be 01XX59D0.
