Hi DrJones, The MaGui can be created as a stadalone mod very easily.
It does not need the use of other peoples Mods like mine or TDW to create.
My own Ui would use 100% the same methods to create as a version of the MaGui one for SH3.
Again most of the work would be done already - All the graphics and page.ini files are basically created for you.
Sh5 is pretty similar to sh3 in how you get things working. The advantage of SH5 is the new menu editor that allows you to visually see items on screen (1024x768) without having to run the game every time you move something to confirm its works
.
Also sh5 now creates a seperate page.ini for each sub page
ie: navigationmap.ini, UZO.ini and attackperiscope.ini
whereas 3h3/4 had all the enteries in one file menu_1024_768.ini.
So to start you could split the menu_1024_768.ini file from the MaGui mod into all its relevant (subpage).ini files [You can find all the relevant subpage in the SH5 Menu Editor] Then point all the graphice from within the Menu Editor to The relevant graphics that you took from the MaGui mod. (Remember to place the files within the Data/Menu folder of sh5 - or you'll CTD.
I would recomend you to look at this tread for some good info:

Also Karamazovew did a great Tutorial on the Menu Editor - You'll defo need this
http://www.subsim.com/radioroom/showthread.php?t=163118, it explains the methods need to place items properly with in sh3/4/5 for scalling etc.
With some practice You'll have no problem getting this working - but you'll need to delve into scripting a bit (In order to get Dials etc to display) but once you have the basics it will be no bother to you (I can help with the scripts to get you going if you wish.
Actually I created a Tutorial here on subsim to show how this is done.
Will find it and post a link:

As I said with a bit of practice The MaGui Mod is pretty much 95% achivabe within SH5 (No difference to my own - I just based mine on Karamazovew sh4 User Interface that he created).
