as far as i can tell all the cheats still work with the current game version.
though, there are just a few caveats...
these apply to the battlecheats.
first, the indicators don't change till you've selected a different follower/pc and then gone back to the one you want to select.
second, you can't use the reset attack command on an opening turn when you lack an opening strike. though if you do have an opening strike (a fairly rare occurrence), you can use this cheat to get your character's attack action back from the getgo.
third, sometimes the cheat just doesn't want to work, just keep trying, sometimes a double-tap works when this is the case. if you're using the restore health cheat and you have a full party, the f6 key can select your 6th party member before the cheat is applied (usually when 6th character is off screen), this can also happen when you have additional forces under your control, and they take up more f-keys... so when this happens try to keep both the characters in view at the same time
finally, in addition to part three... if the cheat is being particularly troublesome, i've noticed that selecting the character in question, hovering the pointer over him/her for a few seconds, then activating the cheat sometimes works too, failing that if you're trying to use the reset attack/movement cheat and it's not working, tapping both keys at the same time can get it working sometimes.
