Hex editing - Tactics Ogre PSP

Hey guys, back in the day, we used to do rom editing for save files to manipulate things. I was never into that but there was an old school niche group that was way into it. To make a long story short I want to transfer my PSP file to my Vita and its not letting me so I was going to hex edit a Vita save file to replicate my characters and items. Any help is appreciated. If you can get my actual save file to work on my Vita I will actually pay you.
