Those cheat do work. There just doesn't seem to be one that can prevent soldiers being sent off to war.
If such a cheat exists (and can be toggled) it would be greatly appreciated if anyone found it!
Why you need it? I finished the game with my first team. Everything you need is a "unlimited training" cwcheat.
Training Unlimited
_C0 Training unlimited
_L 0x201CFC80 0x00000000
_L 0x201D195C 0x24020001
_L 0x201DA810 0x1000000C
* (you'll need to have one permission to enable the training )
And now you can train your team forever! When you need go to Audience, ignore the second option.
