Would you like a ready-to-use Python script for extracting game variables from a Ren'Py save file?
# external_repack.py import zlib, pickle with open("savefile.save", "rb") as f: f.seek(9) # skip header raw = zlib.decompress(f.read()) data = pickle.loads(raw) # modify data data['money'] = 500 new_raw = pickle.dumps(data) new_comp = zlib.compress(new_raw) with open("new_save.save", "wb") as out: out.write(b"Ren'Py S\0") out.write(new_comp) If you just want to edit game variables, use Ren'Py's console ( Shift+O ) or developer menu ( Shift+D ) – no repacking needed. renpy save repack
