I tried using the listed cheats in skirmish mode and they didn't work properly (they showed the "-> 1" though).
I first typed in cheats_2160, after that I tried the money cheat, it seemed to have recognized it, but I didn't get any extra resources. What did work was the "quit" command :P
So, now trainer is forthcoming for this good old game?
EDIT: It would seem the cheats only work in campaign mode, but even then they are not that great help. Damage to units seem quite random when applied to the enemy (sometimes the same units I use deal little to no damage to an enemy unit and takes them forever to kill it, other times same types of units kill the enemy's same type of unit in a single hit), the bad friendly-AI (your units will charge into the enemy as it's shooting at them, and only after dying a lot will finally think of carrying your order to fire back), the gruesomely easy way in which the enemy eliminates your units, and the horribly constructed missions (on the first ED mission, I was told not to mount a direct offensive of the enemy's base, but instead sneak up some infantry in a heli into their base, I did more than that with 3 whole helis filled with the best troops and the hero, in less than a second, their base defenses killed them all and I had to mount a direct offensive and destroy their base in the good old fashioned way, which was what the game recommended against. YAY!).
