Yes.
You need this tool to crack open the historical.database.odb file, then edit the csv files as you wish, then put it back together again. Here's a tip. If you delete the players from the Master.csv, the stat lines of those players are inert. So, the Master is the most important csv to edit, and maybe the only one you need to edit assuming you have a list of the players you want to delete (maybe Stathead at BBR could assist in generating that list).
