Patching Guide! To get RunicPlatinum is a straightforward process, all you need are; PokemonRunicPlatinum.xdelta xDelta Application (Provided) A clean copy of Pokemon Platinum (US rom, for best results use the Xenophobia - 3541 dump) A Nintendo DS Emulator (Desmume was used for testing but it should work with MelonDS as well!) A Flashcard/R4 TwilightMenu++ for 3DS Step by Step: Open up xdelta UI and select "Apply Patch" tab (It should automatically be on this tab) In the "Patch" window, select "PokemonRunicPlatinum.xdelta" In the "Source File" window, select your clean 3541 - Pokemon Platinum ROM In "Output File" window, choose the destination where you want the new file to be saved and give it a name. I'd recommend just calling the file "Pokemon RunicPlatinum.nds" Should be noted that there isn't a custom title screen (yet) but you will know if the patch was successfully applied as soon as you start a new game.
