Hacking Can't found private header with the powersaves

[Skylex]

Hello, I have a problem : I followed the tutoriel following literally : https://gbatemp.net/threads/tutorial-get-your-private-header-using-powersaves.385511/ to extract my private header with the powersaves, I tried with my only cartridges of game : Pokemon X and Pokemon Omega Ruby and I do not see neither the " XX XX 88 " who should precede my header nor 48 "FF" which should be later.. :c

PS : Sorry if my english is bad

Could you find a solution to my problem, please ?
I have already posted on French forums but they did not find any solution :X

Thank you in advance

Edit : I have found a solution thanks to internet, you can delete this subject
