Notes
MAKE SURE TO NOT PRESS F1 TO ACTIVATE THE TRAINER UNTIL YOU ARE AT THE MAIN MENU (this is where you can click NEW or LOAD or CONTINUE)!  THIS IS ESPECIALLY TRUE FOR ALTERNATE RELEASE VERSIONS OF THE GAME!  If you have AOB error when activating, wait a few seconds and try again.

EDITOR OPTIONS

For Ranking Unit Stats options, select a general or high ranking unit, then click to open it's panel to show the values for that unit and the editor will fill in.  Modify the values, then press TAB to lock them in.

Easy Build Buildings:
Toggle on and you can put buildings into the queue, even if you do not have the correct money.  If you need specific Reforms or other pre-requisites, this likely won't work.
