Is there anything really special required to get these to run on your PSP? I know for UMDs and stuff, legit ones, you need the pandora battery and all that. But I'm thinking like I could log into PSN now on my PC here and pay the $6 for Street Fighter Alpha or $10 and Echochrome and they go right onto my HDD, and from there you just copy them onto the memory card as I got a reader on my PC here. Is it that simple to do this? Or do I need pandora or whatever steps to get this way into stuff? Honestly I'm just asking because I'm curious about a pair of PSOne titles but I want to try them out and there's no demo for Alpha or Castlevania Chronicles. And on the lacking UMD front I named one, and then that Stardust Shooter one I'm curious about too.
