need pokemon emerald tips

is there ANY non-cheat way of getting Alakazam on an emulator? if not then how? please help.

Impossible as far as I know. You can't trade between roms without a GBA device.
Cheats are the only way I know of...
You may be able to find someone in game to trade you a Kadabra, so it can evolve, but I doubt it.

so, where and how do i use chests ?
