Sorry, I should clarify - you don't need PSM for Unity if you already have the PSM Dev Assistant. You can use PSM+ straight away (provided you have access to the closed beta on the Wololo forums) with the regular PSM Dev Assistant.

The method using PSM for Unity is mainly for people who did not/could not install the regular PSM Dev Assistant for whatever reason. Because PSM for Unity is DRM-free, it can be installed using the Package Manager - the regular PSM Dev Assistant cannot.

That said, PSM for Unity is supposed to have various advantages such as connection over Wifi as well as USB, potential support for the PSTV, etc.

 

1) I'm not completely sure because I'm not running 3.15. There's no reason why not in theory because everything written in the guide should work fine on 3.15. However, I'm not sure if the PSM for Unity update 1.05 requires 3.18 or works on older firmwares. Try it. You could also try installing the base PSM for Unity pkg without the update.

3.18 is popular because you can use TN-V (PSP mode exploits) and TN-X (PS1 mode exploits) with it, meaning you can use PSP homebrew and isos, PS1 isos etc. That said, those exploits might also exist for 3.15 too.

2) You only need the Wifi on to check your email, I believe. That said, it shouldn't cause any hard to keep the Wifi on because the Vita doesn't auto-update like the 3DS and Wii U do - it will never update without asking you. You should disable it when you can just in case, though.

3) Actually, good point about the PSTV. You should still be able to install it on the PSTV using the recently-released EML Generator. I don't own a PSTV to check, though.

 

great tutorial dude,

I just got one problem on the step 7.

My QCMA wont refresh the database; it will just keep saying that there is no vita registered.

SO in the end when I go in the option to see the PKGs inside the manager on vita the list will always be empty,
Any help?

 

Short answer: Just BUY IT NOW

longest one:
maybe not this way,
but any vita on sale is < 3.51, so you can use another method found on Wololo.net to install the Unity apk.

 

Actually all eCFW and PS1 Loader exploits works on 3.20 (version exclusive to NA Vita TVs) and below. So yeah, they work on 3.18 too. But if needed to update to 3.18 to run actual vita games (either PSN or cartridges) users can try updating to 3.18 using tricks with QCMA or a usb stick if using PSTV/VitaTV (actually I recommend updating a Vita TV to 3.18 to gain compatibility with dualshock 4 controllers).

 

I heard PSM was pulled. I know nothing about PS Vita, so sorry for the question: does this guide still work?

 

PSM+ is now publically available, as is Rejuvenate for Unity! Guide has been updated to reflect this.
