[Available only in Factory OS? It is not possible to enter it on a retail fw.]
 
this is only included in a special factory "reset image" version of the system software,
 
this version has a completely empty vs0: and as such will never boot into the main shell.
 
 
This is emulated via the PSP Compatibiltiy Layer "SceCompat" and is loaded by the module compat_diag.skprx.
 
on startup it will load the dolphin program "simple.prx" into the emulator, the program has a Title ID of "SIMP01042" 


It will show some dolphins and a seashell. In this mode you can test the spotlight performance on the PS Vita.


the entire EMMC of a dolphin vita was dumped using SD boot in 2023. and can be found on [https://archive.org/details/psvita-dolphin-test/ archive.org]
There is no known way of entering/exiting this mode.


but the compat_diag.skprx module can also be found in os0-inactive partition on early vita's that have never had a system update.
It same retail/debug VITA run safe mode on start up and update firmware by game cart.
