I played SH3 with GWX using the jsgme installer for a couple of years. I've just got SH4 & the Uboat missions cd's.
From what I've been reading, I gather there isn't a "management upgrade" zip like jgsme available for SH4.
I need to keep things very simple as I'm a computer numpty, so can somebody point me in the direction of enhancements that are necessary or very desireable, and er, dead easy to do.
cheers
