GBE cheats

[Appoloin]

i have it on a imac and the cheats seem to not work, i know that the cheats are correct because they work on my brothers windows computer. but he wont let me use it so i have to use a imac. so when i go to plug in the cheats it says that cheats must be in XXXXXXXYYYYYYY for mormat or something like that.
so how do i enter in cheats corectly.(these are gamesharkcheats)
Thx
