Bit of a long shot, but anyway...

Having played the game to death the normal way, I've been programming a hack to switch on certain features using a VB.Net Timer, which is working okay.

I'm trying to improve it however by enabling the red boxes that appear when you use a Remote Sentry, or AC-130. Is it possible to enable those red boxes while you're in first-person player (e.g. normal) mode? I've tried a memory search and get about 40 results, but when I try to find "what accesses these addresses" in CheatEngine, it crashes iw5mp.exe.

Can it be done, and if I ask really nicely, can anyone supply the red box offsets? Thank you!
