Toefur: You're in luck! Your question inspired me to replay my old copies of SQ4EGA and SQ1 remake EGA. So now I can post some screenshots here for you.
WARNING: these pictures will take a while to load for dialup users. If you happen to be one, you might want go grab a sandwich.
Moderators, if you want to turn these into links, feel free: I just typed the post this way and am currently too sleepy to bother changing it.
Spoilers below for SQ1 and SQ4, but I doubt anyone will care.
Pictures from SQ1 remake EGA:
The Arcada's scientific data cartridge library
Roger in the Arcada airlock/spacesuit room
The escape pod
This warp-speed effect is different in the VGA version, but I once saw a magazine showing the EGA effect in a VGA screenshot.
These acid drips are a pain: fortunately I managed to apply the NewRisingSun patch to this EGA version
Buying a droid at Ulence Flats
Escaping the Deltaur
Pictures from SQ4 EGA:
The SQ4 title logo: unlike the VGA logo it's based on the original SQ1EGA box art.
The subtitle.
Vohaul's recorded message
Roger falling through the time rip. No multicolored tunnel here!
Roger ponders stealing a timepod
The planet Estros
Another hologram of Vohaul
Roger in the Galaxy Galleria mall
Roger and Roger Jr. shake hands at the end
One thing I did notice that the SQ4 EGA animation is a lot cleaner-looking than the VGA animation: Roger has visible eyes when he walks, instead of a red blob for a face, for example.
