Changes

You have a PSVita/PSTV on firmware version 3.60 to 3.73, you can turn it into a decent emulation device by installing the HENkaku homebrew enabler. If you're on the 3.60 firmware, you can obtain it [https://henkaku.xyz henkaku], for 3.65-3.73 use [https://github.com/soarqin/finalhe/releases Final h-encore]. Those on firmware versions prior to 3.60 can update manually by following the instructions [http://wololo.net/2016/08/09/manually-update-ps-vita-firmware-3-60 here]. Furthermore, on versions 3.60 and 3.65 it's possible to use a bootloader patch called Ensō, which loads HENkaku automatically at boot: [https://enso.henkaku.xyz Ensō for 3.60], [https://github.com/TheOfficialFloW/enso/releases Ensō for 3.65]. It's possible to downgrade firmware version with a tool called [https://github.com/TheOfficialFloW/modoru/releases modoru]. You can use tools such as Vita Homebrew Browser to install homebrew directly on your PS Vita/PSTV.
