Is this old? I haven't really been following the PSP that much. Anyway it allows all PSPs fat or slim to be downgraded. When did Dark Alex come back?

Its a few weeks old. Basically my understanding of it was that it allowed firmware versions to run on hardware that had disabled them. Example being the Slim PSP is normally unable to support 1.50- the Time Machine fixes that.
