Hello, Delta Emerald is not an official title. If it is a hack you are referring to, you should search for its corresponding thread in the ROM Hacking section of PokéCommunity:

If you actually meant Omega Ruby or Alpha Sapphire, you should head over to their section and post your question here:

Pokémon General is actually only for topics that don't fit anywhere else on our forums :) good luck!
