there are some tools for that (I know they exist, IDK what tools avaliable and how to use 'em). what I personally do is pretty simple- trade between them, than take my friend's legit firered cart and trade them to him, then use his cart to transfer them to pal park. its the easiest way. you can also do the transfer VIA emualtors on pc, to an emulator of platinum or other 4-gen game(SS,HG,D,P) then take the save with R4 and send it to my REAL platinum.
