Awesome man thanks a ton! I'm non-jailbroken so gonna see if I can figure this out just to edit my booster points. You're the real MVP.
EDIT: Okay, so something very interesting. I actually don't have a 004.bin. Still tried importing your file and making the necessary changes (deleted 018 as well) but there were no changes to my YGO points. I then attempted to edit the 018.bin with a modified hexadecimal amount for YGO points as you outlined to no avail (gives a black screen). Do you know what might be happening here regarding no 004.bin?
EDIT 2: I even reinstalled the app and logged back in. There's definitely no 004.bin to be found. There are bins 001, 002, 003, 006, 009, 010, 016, 017, 018 and 019. 008 looks the most similar to 004 in your video but again, when edited it just goes to a black screen when I start the app.
