I got FFS and swiftly took some screenshot comparisons of it first:
http://pg.photos.yahoo.com/ph/shinotogipervert/album?.dir=48fd&.src=ph&store=&prodid=&.done=http%I have the ARC and PCE screens next to each other but the SNES screens are last cause yahoo wouldn't accept .bmp so i had to change them to jpgs.
Graphically the Arcade/Neo Geo version stomps everything else.
After that I think it's pretty much a toss up between the PCE and SNES versions.
The graphics on the pce version are a little grittier and there's a black box surrounding the names/lifebars of characters in the PCE version (it's kinda hard to notice in the screenshot i took in DK's stage, so i'll probably put up a better pic later).
-I'll also go ahead and add right now that the black boxes in some form are also present in AOF and SFII' for the PCE.
Still, some of the details seem more vivid in the pce version and inversely some seem more vivid on the snes.
-For instance, in the back-background of duck king's stage, behind the screen to both sides you can see green lights flashing in both the ARC and SNES version but it's pitch black back there in the PCE version.
However, in Mai's stage on the PCE & ARC versions there's a man on a fish(?) that wizzes by that's mysteriously absent from the snes version.
There is also a difference in resolutions.
The sounds of the PCE version are really good.
Seems like they remixed some of though, I don't like the way Duck King's music starts in the non-neo geo versions.
Either way, soundwise the snes version gets blown away by the other 2.
Gameplay-wise, there's some issues in both of the ports.
*Now I'm not familiar w/ high level tatics, move priorities, or frame data in any fighting game prior to SFA3 w/ the exception of SSF2T and hyper fighting to some extent, so I can't get too in depth here.
I can however say that there's some very noticeable speed differences. I can't quite put my finger on some of them, but the SNES version seemed a little faster than the PCE version overall, but not in every aspect.
One move I was able to notice speed differences on in particular was Kim's dive kick (d+K while in the air).
It's definitely faster in the PCE version than every other version. Snes seemed slowest but it's comparable to the arcade speed.
I should also add that the pce version had noticable load times after picking a character.
Not annoyingly so, just noticably.
Not nearly as bad as the NGCD load times for anything, yuck.
Again, the Neo Geo/Arcade version wins in every aspect by no small margin.
Between the SNES version and the PCE version I really can't declare a clear winner, but since the PCE version stomps the snes version in the sound department and neither one is arcade perfect gameplay-wise, I'll give the PCE version the edge.
I'll post up on SF2' a bit later and AOF....at some point.
Might try out and tack on my opinion of the Sega CD version too but I've heard from far too many
reliable sources that it blows chunks in comparison to every other version.
Did I mention AOF sucks?
I really not sure it's worth my time...
