There was discussion of using EUP's to produce uncloaked DT's in a previous thread, http://www.staredit.net/topic/16545/1/

I'd really like to add uncloaked DT's to a few maps of mine.

I never was able to figure out the advanced EUP methods to add large data values to the death table, can one of the cool cats who knows about them figure this out? or tell me not to hold my breath?

I think I tried earlier but the subtract 1 op wasn't working there, only the byte set... so this wouldn't work without finding new overflows or using executable code (don't hold your breath)

I think the only reliable method is turning on shared vision. You can do the vision update trick to never actually reveal fog of war, but if you do that, some of the DTs will blink out of existence every 300 frames.
