First off, about files transferring: How do I transfer files from my PC to the Vita without having to update to 3.57? I installed QCMA but it doesn't seem to work, every time I choose the connect to PC through USB option, the Vita just returns me with "Could not connect to a PC". For the record, I've turned on Airplane mode and restarted my Vita before connect it to my PC. My QCMA setting have "Disable USB monitoring", "Disable Wifi monitoring" and "Offline mode" checked. About remote play: I have a hacked PS3 that is running on Rebug Cobra cfw (if I remember correctly). Can I use my Vita to remote plays it? Is there any restriction (ike limited amount of games or lag or low framerate, etc)? Can I use my PS3 through the Vita, essentially accessing it from everywhere as long as internet connection exists? Last one: About hacking How stable is the PSP emulator on a 3.55 Vita? Is there any noticeable difference in graphics and framerate between PSP games downloaded from PSN store and PSP games play through emulator? It seem like the Vita's native resolution is twice the amount of the PSP's native resolution so maybe when you're playing an emulated PSP game, the game is running at 480x272 resolution but stretched to 960x544 whereas playing the same game downloaded from PSN is natively 960x544? What about video playback? Does playing video in emulated PSP environment means the video is playing at 480x272 and stretched to 960x544 too? Last but not least, can you borrow someone PSN account that already have exploited games on it and use one of those games to hack your Vita?
