Any Gba emulators with cheats?

Does anyone know how i can get a Gba emulator on my iphone that allows me to use cheats on it? Gba4ios doesn't let me:/if you do, mind posting a link to how i can download it? It doesn't matter if i need a windows 7 laptop for it btw.

I have moved to android know but i could never find one when i had my iphone i just played legit you should get an android phone because they are generally better than iphones if you get a good one
