The Flash Games Development thread has been created, and all existing Flash source files have been released, here:

Note that those games are all modified for Beta 2, but should work fine with Beta 1. Nothing has changed, though, so unless you are planning to modify the games yourselves, there is no need to change to these versions.
Oh yea, note that the pre-docs for Beta 2 are also in the second post in that thread, including instructions on how to modify the games. They are worth reading.
