After Windows 98, I couldn't play Aces Of The Deep anymore.
Actually miss the whole Aces series. Aces Of The Pacific was a great one! Was disappointed when they dropped the proposed RAF add-on for it.
Was able to get SH1 with expansion disks to work in DOS Box in XP, but the 64 bit version of Vista has been uncooperative.
I don't have SH5, but I have the other 2. Both games in stock suck. But modded with the supermods available for them, they're both fantastic to play!
GWX 3.0(?) for SH3
And for SH4 there is,
TMO 2.5, Trigger Maru Overhauled
RFB 2.0, Real Fleet Boat
GFO, Game Fixes Only
FOTRS, Fall Of The Rising Sun
So although SH4 didn't get the attention of SH3, there is a nice list of supermods to choose from, and some cool little mods that will work with them, but be careful when adding them.
