Hacking My Private Hheader!! HELP!!!

[TheMaster11]

good morning to all , I wanted to ask for information about a Header in backups 3DS .
I wanted to ask , I have one backup of the legend of zelda ocarina of time and one of Nintendogs + cats , are all two of 4Gbit , I wanted to ask if I can use these to comfort one of two header ( 4 Gbit ) other backups more large ( for example, 16 Gbit and 32 Gbit ) or there are problems ? if I try to patch the backup header with smaller (like my 4 Gbit on a 16 Gbit ) what happens ?

I wait and thanks

When you will inject your header to 16Gbit ROMS with Gateway ROM Matcher, it will ask you to fix thé header automatically
