Hello all, Im new to custom firmwares and I've done a little research about hacking my PS Vita but im not extremely confident. Im wondering what is the best CFW or guide to follow in order to play PSP ISO's and possibly Emulators on my PS Vita running Firmware 3.15? I dont own a PSP so im mainly interested in playing Final Fantasy Type 0 on my PS Vita along with Crisis Core but if I could get a Gameboy Emulator/Nintendo or something to play the old pokemon games that'll be great! What are my options? Is their only one 'PSP Mode' hack available or do I have a few to choose from? Also is it possible to undo a hacked Vita? Install the original firmware if need be or change CFW? Im also assuming my original Vita games will play with a PSP hack?
