Hello Bombomadil here with my new mod:
The Sovereign Refit v1.1

New in this version:
regenerative sheilds, yacht laucher special weapon
for the sovereign and battle bridge section

-----------------------------
Build Time: Along Time plus a while for this version
email: bombomadil@hotmail.com
homepage: N/A
-----------------------------

ok now for the install instructions:
step 1.
put the textures in the textures/RGB directory
put the odf's in their odf directory
put the sod's in the sod directory
put the bitmap's in the ship images/admiralslog/bitmaps
put the .h file in the a2 main directory

step 2.
you can put the gui_global.spr that came with this zip file in the sprites
directory or you can go to the gui_global.spr of the sprites directory
and scroll down to the special weapon bottons and
then put in the these lines instead of the lines for the galaxy seperation:
b_ggalintegrator gbsovsep 0 0 64 64
b_ggalseparator gbsovsep 0 0 64 64
b_gsovyacht gbsovy 0 0 64 64

now scroll down to the wireframes section and the wireframes for fbbridge and fsaucer
and replace them with these lines:
fsaucerw1 fwsovsep 0 48 48 48
fsaucerw2 fwsovsep 48 48 48 48
fsaucerw3 fwsovsep 96 48 48 48

fbbridgew3 fwsovsep 96 0 48 48
fbbridgew4 fwsovsep 144 0 48 48
fbbridgew5 fwsovsep 192 0 48 48

step 3.
go to your tech1.tt file of your techtree directory and put in this line:
gsovyacht.odf 0 //sovereign yacht launcher
or you can put the tech1 file in the techtree directory replacing the one thats there

step 4.
play the game and enjoy!

*note: on step 2 and 3 if you replace the files you will probably lose
already installed mods
