NOTE: I made this on a game that includes the altered sprites from the Miranda Class (In the thread called 'Help with Importing ships'), I am not sure if it works without those altered sprite files.

//*********************************************************************************************************
Open 'Gui_Global' (C:\Program Files\Activision\Star Trek Armada II Fleet Operations 3.0\Data\Sprites) and look for: 

all_alliedrepairw5	wireframe10	96	96	96	96		#		

add beneath it:

rom_shadoww5	wireframe10	288	384	96	96		#		

//*********************************************************************************************************
then find:

b_rom_rhienn_pulse	romulanbuttons03	428	173	80	80		#	6	3

and add beneath it:

b_rom_shadow	romulanbuttons03	258	428	80	80		#	4	6
