Well you can simply use easy adrenaline installer.
https://github.com/Freakler/vita-AdrenalineEasyInstaller/releases/tag/v1.15

Install VPK, then it can setup adrenaline, just do what you do with a normal PSP with CFW. The Folder on vita is ux0: PSPEMU (That is Basically the entire psp memory card on vita and adrenaline)

 

Yep actually it still needs activation and Sony did something against it (or maybe it was against PS4 MTX modchip ?!). Anyway actually there's no way to activate PSVita on 3.60 firmware, TheFlow said that it's possible to modify Adrenaline to make it works without activation but he will not have time to do it before September (that isn't that far).

 

Vita games you can, you mean PSP or PS1 games ! Well, you can always use PCSXRearmed core from RetroArch concerning PS1 games ! Its run pretty fine but I still prefer having PS1 stuff on Adrenaline. Just to wait till September.

 

Yes it is ! Adrenaline Easy Installer v1.15 : updated for Adrenaline-5.1. Its simply that activation don't works anymore.

 

So I just got a 3.60 vita slim with Enso, I have a PS3. How can I activate it to get adrenaline working?

 

I haven't been on the psx adrenaline mode for a while because I know the popsloader doesn't work and many of my favorite games incompatible, so I simply use retroarch and it works fine, did they make popsloader work on adrenaline or is it that your favourite games are compatible on adrenaline stock without popsloader?

 

any slowdowns ??? and can it work with overclocking ??? want to do megaman x series , spyro , and legend of dragoon

 

That doesn't work since Sony borked system activation...

 

Hm how does one check if it's already activated as I bought it second hand and it wasn't factory wiped? I think...

 

Just got home and checked. No files in my npdrm folder...
