You really need not bother with the physics of a roulette table if you know the statistics that you will be working with. The trickiest part would be make the flash animation match up with the computer generated results..... but it could be done. You really are not actually emulating the table, or shouldn't be... just grab a table, do 2,000 or so tests on it and find out the frequency of each number and color.... than use that information to weight a random number generator.
I am confident that is how most online casino's play...
You will probably not find such games readily available for a cheap price though, since that type of software... designed intentionally for use in an online casino is usually in-house developed to integrate with databases with payout information and what-not.
On the other hand if you want to pay me to develop such software for you I would be more than willing to do so... just send me a private message
