The "data" patch is all the data tables as exported from the spreadsheet, so it contains most of the changes from the hack. 

Spreadsheet is here:
https://docs.google.com/spreadsheets/d/10WVUMvbF2XVRt8ChQB5MBTC3y2D7nbakVGbRomoo97k/edit#gid=1610469323
If you want to mess with it, make a copy and then start unhiding stuff (and good luck figuring out the madness).
This data IPS is generated by the "Export" sheet from there.
