A bit of an off topic post, but here's how to load cheat codes in the Delta emulator when playing Pokémon Emeral to catch all three starters. That's something I had to figure out today so my son could have all three starters.
First of all, I'll assume you already had Delta installed, Pokémon Emerlad launched, and have gotten to a point where you can catch Pokémons.
Loading cheat codes in Delta is straightforward and you can read the official page for how to.
What took us some trial and error was finding the right master code to use.
The one that worked for us in the Game Shark tab was B749822BCE9BFAC1 A86CDBA519BA49B3.
Followed by:
- Treecko
A8AF08CF 3BEC2145 - Torchic
BF2729CF FF00080C - Mudkip

These worked on Delta 1.7.2 for iOS.
Most of the info found via this Reddit post.
Enjoy!
