Gaming Is it safe to play Pokemon Platinum cart

[Chris_Skylock]

Just wondering why Pokemon Platinum genuine cart uses 256KB save file according to NDS WiFi Back Up tool? Is it safe to play the game on its own? If I migrated my Acekard 2.1 Pokemon Platinum Save file using PokeSav, it was saved as 756KB, I ported it to my Pokemon Platinum Game cart and it runs fine. Though, My Battle Recorder Videos were deleted. Is it safe to continue using my ported save files?

I just got my Pokemon Platinum awhile ago from my mom. I didnt have any answers from PokeSave Community. I also used the search button and nothing came up.

Regards,
Chris

EDIT: I just migrated my flashcart Pokemon Platinum to my retail one and I edited the trainer. How come it was on its previous data than the ones I added like Trainer ID, new trainer name, 1 shiny eevee
