[HELP] How do I edit text for Corpse Party Blood Covered - Repeated Fear

So... It's gonna be a year until the people at XSEED decide to translate CPBCRF. So I'm wanting to translate 'Most' of the story, since it's been translated already. (Only part that hasn't is the exclusive new extra chapters. But those will be for another time...)
I know NOTHING about ROM Hacking. I DO know what the translated story is. Can anyone help me figure out how to edit the text?
