Questions About PS1 Games On The PSP

So I see Playstation has released the PS1 classic Spyro: Year Of The Dragon for the PSP. I want to get it because that was one of my favorite PS1 games, but I have a few questions first.



1. How is the transition from PS1 to PSP for these classic games? I imagine the camera might be hectic because of the lack of a second analog stick. And if it is like that for PS1 games on the PSP, I may reconsider getting Spyro.



2. This may sound stupid, but I am a little confused about the info of the PS1 games in the PS store, they all say something about not supporting memory cards. Does this mean I can't save my game after playing?



3. What is the official PS1 emulator? Is it something I need to get before playing PS1 classics on the PSP? If so where I am I supposed to get it?Questions About PS1 Games On The PSP
