these are tools for modding pvz2. they are currently very incomplete but I will start working on them again now.
you're currently best off looking at other places for pvz2 modding tools.
like this other repo or the sunflower nation discord

what you need to run

python 3.10+

what it can do so far

unpack the obb
extract all of the file names and save them into a json file
use a json file with those file names and add them back into the obb
unpack most pgsr (aka rsgp) files

thanks to:

the plants vs zombies 2 quickbms script for some of the documentation this repo that documented more of the lbsr header struct
