The cheat "process_rc" DOES work, just not through the console IIRC. You have to activate it through a script..which would involve exiting out of EB, editing a script, letting it load, activating it...and you would need some knowledge on programming.

Not worth it if you ask me, the "create_unit" cheat is a much better option. Just subtract money equal to the cost of the units you used if you want to simulate a realsitic effect.
