This file is used in the console by typing

bat training

The allowed number of training per level will be set to 555 (that should be enough for any purpose). Even if you are in the middle of a training session, and are not permitted to go beyond 5, just open the console, type bat training, close the console and hit E to train a 6th time, the numbers will be automatically updated. There is no need to leave the dialog.

Installation:

Download manually or with the download manager and install as usual. MO will complain about "No game data on top level" just ignore it and install.
