FDS:Flying Disk System. It’s a “specification” of the PSP first version. You can shoot UMD when you play a game.

It also my reason why I haven’t get PSP…
Today I found a funny movie about this issue.

The golf game said “Nice Shot!” but… :-)

You can see other movies, whew… I also found PSP playable…
