Funny, I tried it out just some days ago. I was playing a bit of Virtua Striker, I had 4-5 (betas also) versions, most were running very slow, and one version was running way too fast, I didn't find an option to slow it down to normal speed.

Spikeout was running fine, was also playable, not a really good game though.

Harley Davidson & L.A. Riders was absolutely not playable.

Daytona was playable, yet there were several problems, controlling the car was way too sensible, had problems driving straight.

I didn't try Star Wars, so I can't tell you if it's playable, and I also cannot test it anymore for you, as I deleted everything. I had to make some space on my NAS, so I was going through my sets, and I deleted quite a bunch.
