I plan on getting a vita and a ps4. Id like to run all the old emulators and psp isos on my vita as well as using the remote play feature that the ps4 has to offer. I plan on getting a vita running on firmware 3.15-18 and keeping it there since only the old vita games appeal to me (mk, killzone, sfxtk, mVc, need for speed, etc.), putting all the emus on it and then would love to remote play games like RE remaster, killzone, etc. would all this work on 3.15? thanks again. Im sorry if im not taking the time to do all the research to get my answers, but the gamestop about an hour away from me has a white vita and will be near there today. Thanks guys!
