To curb hacking the PSVita via the Trinity Exploit, Sony surprisingly released FW 3.71 about a month ago (or 2.5 months after the TheFlow released the Trinity Exploit chain which can be used to hack FW 3.69/3.70). As a result, the latest PSVita firmware is unhackable and for those stuck there, CBPS Team have come up with a solution letting you play PSP games called Chovy Sign. Other than that, we’ll also be looking at the efforts done by Reddit user ‘JimiHeff’ to port MorrowindUnity to the device!
Chovy Sign Public Beta released – You can play PSP ISOs (backups) on PSVita FW 3.71 if you can figure out how
As Sony decided to bundle the PSP’s GPU and CPU inside the PSVita’s motherboard, it can emulate every PSP game out there perfectly but since it can’t accept UMDs, only PSP games available on PSN are officially playable.

Chovy Sign lets you play any PSP backup on FW 3.71 but make sure to check out the linked video to use it as it comes with no instructions!
However, through hacks, you can play any PSP game you want on your PSVita provided you have an ISO and even use XMB/plugins/themes if the ePSP solution you’re using provides such features. On firmwares below FW 3.71, the best piece of software to use for PSP emulation is TheFlow’s Adrenaline which not only lets you play PSP games but also lets you run homebrew that requires 64MB RAM, do savestates and use screen filters among other things.
However, as mentioned above, FW 3.71 doesn’t have the luxury of a native hack so CBPS Team decided to release Chovy Sign (which is the first release in Project Chovy, a toolkit for PSP stuff on the Vita), to allow folks with a PSVita on FW 3.71 some PSP action! From its somewhat poorly written README and release page, all you need is the following to run any PSP game on FW 3.71:
- Any working PSP game installed from PSN, even demos such as “LocoRoco Midnight Carnival” and “Petz Saddle Club” work if you don’t want to spend a dime
- Apparently, Chovy Sign works by exploiting the PSP bubble cloning issue which means that if you delete the base game, the “license.rif” (required for PSP games to function on the PSVita) used by clone bubbles is erased and you have to reinstall the base game again
- A good quality ISO dump of the PSP game you want to play since poor dumps may not work properly
- A Windows computer to use the tools provided below
- As there are no properly written instructions on what to do, it’s highly recommended you follow this video by Nagato which details the process in a step-by-step fashion.

MorrowUnity (TESUnity) being ported to the PSVita

Eventually, you might be able to enjoy Morrowind’s map on the PSVita but don’t expect the full Morrowind experience as TESUnity is a map viewer not a game engine!
While Chovy Sign is pretty exciting for those stuck on FW 3.71, those who aren’t are probably more interested in native homebrew developments for the console with the latest news being a potential port of MorrowindUnity to the Vita. News about it emerged a few hours ago on Reddit when user ‘JimiHeff’ shared a YouTube video of a partially functional port of MorrowindUnity (TES Unity) running on the PSVita which doesn’t get past the initial screen. MorrowindUnity/TESUnity isn’t an engine for Elder Scrolls: Morrowind but it’s a world viewer so with it, you’ll be able to explore Morrowind’s world but don’t expect to be able to enjoy the game in its full capacity.
From the video, it seems that the application can’t access the data folder being passed on to it and refuses to continue further with an error reading ‘The path is not valid’. Now, the scene member behind the port has promised to ask around on the VitaNuova (Rinnegatamante’s community for PSVita homebrew development and bounty creation) Discord for help which may mean that you’ll eventually be able to explore Morrowind’s world on the PSVita!
Conclusion
Obviously, it’s no use to be able to play PSP games on your PSVita without knowing what to play so if you want some recommendations, check out this article about some great PSP titles to play. On the other hand, if you’re interested in more Unity stuff on the PSVita, you should check out this Reddit thread about Unity’s Adventure Demo being ported to it.
