ff7lib

A library for editing Final Fantasy VII game saves. Bring back Aeris! Max out your gil!

Made using information from the Qhimm wiki.

Please note that this is still experimental and incomplete, and does things like adding functions to the prototype of the struct library, which it uses underneath.

Reading some information:

const fs = require('fs');
const FF7Lib = require('ff7lib');
 
const rawbuf = fs.readFileSync('save00.ff7');
const savefile = new FF7Lib(rawbuf);
 
const leader = savefile.getpath('saves.0.preview.name').defftext();
const location = savefile.getpath('saves.0.preview.location').defftext();
const gil = savefile.getpath('saves.0.preview.gil');
 
console.log(`Leader is ${leader}`);
console.log(`Location is ${location}`);
console.log(`You have ${gil} gil`);

Changing FF-Text fields:

savefile.getpath('saves.0.character-records.4.name').enfftext('Nanaki');

Changing numeric fields:

savefile.setpath('saves.0.stock.gil', 9001);

Saving (recalculate the checksum on the edited block first):

savefile.getpath('saves.0').checksum();
fs.writeFileSync('save01.ff7', savefile.buffer());
