Clueless about Gameboy Advance Cheats

I've got No$Gba, most recent version, and I'm lost with the whole cheating thing... I've looked around, not only on this website but around others as well.I keep getting these error messages:
If anyone could really help me out, perhaps step by step how to properly download/run cheating tools and use them with games?I will be very grateful for your assistance, thanks!

NO$gba emulator plays DS games not GBA games

Not sure about that one, I got Pokemon Sapphire and Metroid Fusion to work on it.

no$gba is able to play both GBA and NDS games.Have you tried redownloading the game?

Yes I have. Any ideas what the problem could be?Edit: or possibly use a different emulator like Visual Boy Advance? I think I'm just not extracting the cheat things right, or not opening them with the correct program *which I have no idea, I guessed the emu itself*

What game is this?

Oh i didn't know that.
Sorry

Pokemon Sapphire :DI'm fine playing Metroid without cheats..---

RemnocaI recommend you use No$GBA and then use Action Replay cheats with it.

How would I "use" Action Replay for the emulator? o.o I'm sorry if I'm on your nerves about this, getting a little frustrated.
