I made Final Battle Rival! from Pokemon Origins play for Serena without a perfect loop and Custom Trainer Battles should be able to be done with Pk3DS: https://projectpokemon.org/home/forums/topic/34377-pk3ds-3ds-rom-editor-randomizer/, but I don't know how to edit the music in US/UM, I do know you have to dump the game and decrypt the dump, by dumping the game with God mode 9 and decrypting the CIA or CXI, the instructions for decrypting can be found here: https://gbatemp.net/threads/tutorial-how-to-decrypt-extract-rebuild-3ds-cia-cxi-files.383055/

Thank you so much! Will try this later!

Also,do i need to download ultra sun cia to make everything work?

Or i need to dump my game?

You can do either one, dump or download the cia, and use asia81's packhack which I recommend, or use ctrtool to extract the cia.
