You don't need a trainer at all for this game, socom100 posted everything you need. Just edit the file to stop your stress control/energy/food from decreasing over time. Just change the values to 0 like so:

<_generalManager_statusHungryDecWithTime>-0.09</_generalManager_statusHungryDecWithTime>
<_generalManager_statusEnergyDecWithTime>-0.0</_generalManager_statusEnergyDecWithTime>
<_generalManager_statusStressDecWithTime>-0.00</_generalManager_statusStressDecWithTime>
Notice I didn't change my hungry value from 0.09 to 0.00 because I wanted that to continue to decrease over time.
As of now, really don't need a trainer for this game.
