Hey folks. I'm starting out in the vita hacking world and I have a tough question. Will be getting a brand-new vita and updating it to 3.18. I currently have a stock ps3 with latest firmware and a stock ps vita with latest firmware. What I'd like to accomplish is to get all my ps1, psp and ps vita games bought from PSN (which are already in my latest FW vita) to the new older FW vita. I heard there are methods using either ps3 or a vita. So would you guys be able to tell me if there's any difference or I can safely use both devices with the exact same results?
