Playstation one on PSP????

Hi has anybody seen the download for the alpha PS one Emulator at psp hacks??? I downloaded the file but havent a clue what to do with it Is this true, or is it to good to be true

no, its true....but nobody even wants it.very sad...it runs at half a frame per second. so it takes two seconds to go throught on frame......TOO SLOW! and i was very sad myself that nobody has one out yet
