Yeah, although it would be nice to find a way of scaling down 50Hz games to a 60Hz screen, in order to run all of the PAL games one normally cannot run when using a regular TV set (not talking about 1084 monitors etc).
Scaling down? You mean scale down the extra lines that PAL screens have rather than loose the bottom of the picture? Not really possible without introducing black borders. It would contort the aspect ratio.

How does this work on modern consoles? Unlike their retail counterparts, the Playstation/Xbox developement kit systems allow a PAL/NTSC software switch
The retail versions support PAL/NTSC software switch if hacked ;-)

so the game is always scaled up/down to a different resolution without having to rewrite the software
Not true. Games written for 576@50Hz, but run at 480@60Hz loose the bottom of picture. They are either written with black borders in PAL, or re-coded for NTSC.
Usually they are coded for 480@60Hz and just left with black borders at 576@50Hz

How do they achieve this?
They don't.

I'm pretty sure it's impossible to do with the Amiga implementation, but if anyone knows how other systems cope with this, that would be nice to know. :-)
With ECS you can switch from 576@50 to 480@60 but you'll loose the bottom of the picture, and some games coded specifically for 50Hz will screw up. Modern games consoles cannot be written to require specific VBL timing these days.
