Hacking "converting" 544 kb sav's to 512 kb

[Isabelyes]

so, I've got some saves that somehow became 544 kb, while they should be 512 kb.
I was wondering; how can I make them normal again?
because some games fail with them

I would just restore from a recent backup. Another option is to use a hex editor and delete the additional bits (although depending on what caused them to inflate, this may not work).

my most recent backup was made one month ago.

also, a lot of saves are 544 kb now, and i don't know if that affects them either.
and I'm a complet noob with hex editors...

*UPDATE*

files are randomly going 544 kb.

F.E: pokemon ss save: 512
Pokemon ss save backup: 544

and picross' save went 576

even though I just formatted my sd card...

EDIT: I found the solution. just: Rom Settings -> Save Type: 8M
those three saves are 1 MB now, but hey, they're working!

My two threads asking for help can be closed now!

PM: thanks for your advice, Rascal!
