1) The controls on the emulator can be mapped to the buttons on the pad (at least the N64 emu that I saw on a youtube vid could; don't know about the other emulators)
2) Any PSN game can be downloaded and played on the device, but you (obviously) have to buy/DL it through PSN. I'm pretty sure there are many psp/psx rpg games in PSN. Please note that any content previously bought on PSN will NOT be able to transfer/redownload to your device (which is a bummer).
There is no PSN on the Xperia Play, and the Playstation Suite still ceases to exist, you download everything through the android market. There are NO PSP GAMES FOR THE XPERIA PLAY, and only a few psx games available in Europe for download (only Crash Bandicoot in the US, which comes preloaded on the phone).
