Since all of the of the Sega forums fall under Dreamcast (note, can we get one general Saturn forum, please?), I'll make this post here.
I've been using SSF since 0.04 Alpha R3. It's had many updates, and I haven't played many games with it. Under the advice of a few, I tried Yabause 0.9.3 today, and compared it briefly to SSF 0.9 Alpha R4.
First, my system:
Windows XP SP2
Athlon X2 3800 (dual-core 2.0ghz)
2GB Ram
Geforce 7900 GTO 512MB
X-Fi XtremeMusic Sound card
The games that I've played the most on SSF are Shining Force 3 Disc 1 (USA), Dragon Force (USA), Guardian Heroes (USA), and Dead or Alive (JPN). All four of those games run beautifully under SSF 0.09 A-R4. GH was a game that game me serious issues for awhile, and Shining Force had issues with spell effects, but now they run amazingly.
Despite not having enhanced graphics yet (IE, ePSXe), there were some benefits to playing on SSF as opposed to my Saturn. First off, Guardian Heroes' slowdown was nearly non-existant on the PC. Also, sound skipping in SF3 (a major issue on the Saturn) didn't occur in SSF. I'd say that the games ran over 90% faithful to the Saturn, with the 10% difference being more positive than negative.
I only tried Shining Force 3 on Yabause, and I must admit, I didn't give it much time. The game had a blue tint through the title screen, the opening movie would not play, and it crashed on a few attempts before finally rolling. The game and sound would slow down.
For my system, and the games that I primarily play right now, SSF kills Yabause. However, I've heard differently elsewhere. It's not hard to download and try both, so I'd recommend that any serious Saturn fan try both.
