PSP/PSX games

[Mackerel]

so im relatively new here and to evangelion fandom as a whole
however i am curious on whether or not i can play the PSP and PSX games on a PSVita?
i own both a PSP-3003 and a PSV-2k/slim but only my vita is homebrew activated
so i was wondering if i could use it to play stuff like the gfos1 and 2 psp and psx translations through something like adrenaline?
sorry if this is a stupid question

[Axx°N N.]

Yes. PS Vita natively emulates PSP and PSX, which is why there were select titles available to buy and download digitally through official means. Adrenaline is just a means of using said built-in emulation to load any game from those systems you would want, including fan translations.

Retroarch emulates anything else the Vita is capable of (from a hardware perspective) but not natively in its built-in software, such as SNES titles.
