[BF2] Nametag Delay Hack

[TyranO]

To quote myself:

Well this is pretty much a failed experiment. I tried to make a nametag hack that just edited delays in order to work. It does work, but there's a problem:

It also makes delays longer for stuff like ammunition and med packs so after a while when there's too much stuff on the screen the enemy tags start to disappear. It was undetected when I tested but consider it detected now as it's public.

Good news though, it's open-source!

To be more precise, I edited the fade delay, another fade delay, the time before the tag appears when you point your gun at the enemy (0.6 seconds to 0 seconds if I remember well) and the death nametag fade delay (pretty useless).

Two of the offsets in dissasembly were protected, had to use VirtualProtectEx(). Also, in order to figure out the addresses, I used ReadProcessMemory() for reading the 4 bytes of the addresses stored at other addresses. Each byte of the address written in little-endian is read and with some math, stored back into a real, usable address.
