Ah possibly, my bad
But if TS1 is anything to go by, read the games data files for monster and dump each field as a 4 byte integer for the majority of things unless its text. (Just code a tool for this)~
And you can make a spreadsheet its likely a similar layout and identify the pet rates and what not by the pet ID you will see. (Items file will contain these as 4 bytes right before the name).
