[Graphics] (Platinum) Inserted graphics will not display in game

So I have a bit of an odd issue. I am doing a graphical hack of Pokemon Platinum. Exporting, editing, and re-inserting the graphics into pokegra.narc works perfectly fine. The images are the right format (8BPP 16 color indexed), they display correctly in PokeDsPic, I write to the .narc file, and I use Nitro Explorer to reinsert the .narc file into the rom.

But when I load the game and get into a battle, the Pokemon's edited graphics do not show up. I tried editing Bulbasaur, for example, and inserted the new sprites and palettes over his, items 6-11 (and then making him a wild Pokemon to fight in game). But in battle, just regular Bulbasaur shows up.

Am I editing the wrong file? Or is there a step I am missing somewhere? The file I'm editing is root/poketool/pokegra/pokegra.narc

You are, the pokemon graphics are stored in pl_pokegra.narc. Just make sure you use the version of pokedspic for platinum and heartgold.

pokegra.narc is a leftover from diamond. The file actually is used for features like the pokemon dressup minigame (since you can share your dressed up pokemon with other players so you wouldnt want a different sprite to mess that up), probably contests and other things. If you're completely replacing pokemon with different pokemon I'd reconmend editing that file, otherwise it can be left alone.

Ah ok, well that explains everything. Thank you for the help!
