K so you want to know that if a system can play the games from another system that use an entirely different media, DRM, and other security and techno mumbo jumbo that would prevent it from being played on another system, made by an entirely different company without any means of adaptation. Am I understanding correctly?
Answer is a flat NO.
Now if you are asking if the 3DS is powerful enough to emulate the PSP and play PSP games at 100% ability... Doubtful but we won't know until the special people try. I'd go with no due to usually needing double the power of a system to be able to emulate it at 100% capability with no graphical, sound, or gameplay glitches.
Now if you are asking if the 3DS is powerful enough to play PSP games if the games are just straight ports with the only changes being controls and the medium used, then yes it is more then capable.
Did I cover everything you needed to know you silly troll?
