for the never tested :
tour of duty is pretty much like paint in black (new caracter names and a no-cd exe that overwrite the original)
streets of vietnam contains a new menu gui and a map : hanoi 1.0 (by junglelord & float)
midnight marauders contains a new gui , new menu , new ingame txts , new hud , new caracters name , new caracters & gear textures , a semi-automatic mode and some details i haven t noticed , but it seems it only works fully with the AME version.
stfvc mod is just containing a new menu gui
