Developer SMOKE just released version 1.0 of his NES emulator for the PS Vita, NES4Vita.
This new version fixes some stability issues and a specific sprite bug from the previous releases. NES4Vita lets you load several roms that you have to copy in cache0:VitaDefilerClient/Documents/ or any subfolder in there.
How is NES4Vita different from other NES emulators on the PS Vita such as NesterJ?
NES4Vita is a “Native” NES homebrew. It uses the “full” power of the PS Vita, through the Rejuvenate hack. By comparison, NesterJ is a NES emulator designed for the PSP. NesterJ that can also be run on a PS Vita, but with the limitation that a PSP would have.
In other words, NES4Vita has the potential of becoming much more advanced than a “traditional” NES emulator running on the PSP. It’s of course a bit early to tell how the additional CPU cycles will really help (NesterJ was pretty good). This is a relevant question, in particular for an old school platform such as the NES, where a PSP was more than enough power to have something decent. But the sky’s the limit at this point.
NES4Vita: How to install & Run
NES4Vita requires the Rejuvenate hack. Assuming you have a PS Vita running firmware 3.51 or lower, you should be able to run NES4Vita through the rejuvenate hack. Details on how to install rejuvenate and how to install homebrews can be found on our rejuvenate page. Enjoy!
