I recently bought a new Vita slim dirt cheap and started reading up on hacking. My vita came with OFW 3.15 and have a few questions. 1. Can I stay at OFW 3.15 and install eCFW (TN-V10) using one of the exploited games? Or do I need to update to 3.18? 2. If I can stay at OFW 3.15, can I use Gladiator Begins DEMO (because I don't want to pay for the actual game) since the exploited games list says it works under 3.20 and below? It might sound like a stupid question but I just want to make sure. 3. Is PS3 the only way for me to download it into my Vita? 4. Does a PS3 have to be on a certain firmware or hacked in order for me to download the game on to Vita? Or is it just as simple as the instruction? Thanks a lot for helping me out.
