A PlayStation Vita to Horizon OS (Nintendo Switch OS) translation layer (not an emulator)
PlayStation Vita (ARMv7 CPU) executables can be run natively on Nintendo Switch ARMv8 CPU in 32-bit execution mode.
When loading a PlayStation Vita executable, vita2hos redirects the module imports of said executable to jump to routines that implement the same behavior, by using native Horizon OS services, like the one exposed by the original PlayStation Vita OS modules.
-
Copy
vita2hos.nsp
to your microSD card (i.e. to:atmosphere/vita2hos.nsp
) -
Create
atmosphere/config/override_config.ini
and add the following lines to it:[hbl_config] override_any_app=true override_any_app_key=R override_any_app_address_space=32_bit ; adjust the path according to the location of your file path=atmosphere/vita2hos.nsp
-
Note: As long as this file exists you won't be able to use the homebrew menu and instead will always run vita2hos.
A quick workaround would be to rename the file and restart your Switch. Unfortunately
override_config.ini
doesn't allow multiplepath
entries which is why it has to be done this way.

-
Copy a PlayStation Vita executable (
.velf
or.self
/eboot.bin
) to the root of your microSD card and rename it totest.elf
-
Boot (or reboot) your Switch and start any game while holding down
R
- Attempting to use vita2hos via applet mode (album button) will currently result in a fatal error and wouldn't be recommended anyway.
-
Enjoy!
- Copy a PlayStation Vita executable (
.velf
or.self
/eboot.bin
) to the root of the microSD directory (File → Open yuzu Folder →sdmc/
) and rename it totest.elf
- Disable Macro JIT (Emulation → Configure → General → Debug → Disable Macro JIT)
- Run
vita2hos.nsp
- Enjoy!
Make sure to use a very recent build of yuzu, such as Mainline or Early Access Builds.

Copy a PlayStation Vita executable (
.velf
or.self
/eboot.bin
) to the root of the microSD directory (File → Open Ryujinx Folder →sdcard/
) and rename it totest.elf
-
Extract
main
andmain.npdm
fromvita2hos.nsp
to a directoryUsing hactool:
hactool -t pfs0 --pfs0dir=vita2hos vita2hos.nsp
This will extract
main
andmain.npdm
to a directory namedvita2hos
. -
Disable PPTC (Options → Settings → System → Unselect Enable PPTC (Profiled Persistent Translation Cache))
-
Load the directory containing
main
andmain.npdm
(File → Load Unpacked Game) -
Enjoy!
- vita2hos depends on @gdkchan's Ryujinx
codemem2
branch - Some ARM Thumb instructions are not yet implemented on Ryujinx
This is still in very early stages and therefore it can only run very simple CPU-rendered PlayStation Vita homebrews.
There is very initial 3D graphics support (it can run vitasdk's GXM triangle and cube samples by hardcoding vita2hos's GLSL shaders to match the Cg shaders the samples use).
A few noteworthy teams/projects who've helped along the way are:
Also special thanks to @PixelyIon and @SciresM for their help, and to all the testers, especially @jeliebig.
