Welcome to subsim!
As for you question: 1.4 is the last patch for SH3.
And you can only install GWX on a fresh install with the 1.4 patch!
For saving you need to hit the escape "Esc" key and klick save or save and leave in the menu! You can save in Campaign and single missions!
There is no quick save key if that's what you were looking for!:hmm:
But a bit of warning! Saving is risky! Sh3 has some bugs when it comes to saving!
So to avoid those you must follow a few rules:
Never save while submerged!
Never save while near convoys or in harbors.
Never save near scripted units/events!
Otherwise your might bugger up your save.
See you around!
