 I have already tried TWL but it says that it is an unsupported file type and then just closes the software along with homebrew.

Thanks for the reply. Do you have any recommendations on another save manager? I tried using JKSM but from my understanding it only works on 3ds games and not NDS. Worse comes to worst I have a Diamond cartridge that I can use and I get a not empty save from checkpoint that way. I was planning on importing Pokémon using pkhex onto that diamond game and then trading it over to my platinum; however, whenever I try and restore a pkhex save into the diamond cart it says that it is an unsupported file type. I would ideally like to find another save manager first though so I don't have to use another game. Thanks!

I currently have a copy of Platinum, and I want to edit its save file with pkhex. I saved it using checkpoint but when I go to check my save on the SD card, the file is completely empty. Is there anything I'm doing wrong? Thanks!
