PSP emulators for android

Hey guys I recentley downloaded the emulator ppsspp for my device and didnt tested it because i dont have any games. So can you tell me a site for psp games download and as .nds is for nintendo what is for psp

we have psp games here. PSP is either .cso or one of the cd image formats.

PPSSPP can run these psp extensions; .iso, .cso, and .pbp. However don't quite expect it to be able to run all games, there are some that will work partially (with some in-game features not accessible or working properly), glitching, or even not work at all.Speaking of this emulator, the latest version recently released (Oct. 4th 2015) is v.1.1.0.
The changelog note is as follow:

Support for ARM64 on Android, for improved performance on new devices. Has some new optimizations.
Support Android TV, like nVidia Shield TV
Screen rotation on PC, useful for vertical games like Star Soldier
Many minor performance improvements and compatibility bug fixes
GPU emulation fixes like correct depth rounding, fixing text in Phantasy Star
Other graphical fixes like UV rotation
Support savestates for homebrew apps
Simple integrated "Homebrew Store" to download PSP homebrew apps
Minor AdHoc multiplayer improvements. Still many issues left.
Disable a dangerous optimization on ARM, causing walk-through-walls in Tenchu
sceAtrac music compatibility fixes, fixing noise in a few games
Better texture scaling performance
Direct3D closer in features to OpenGL
Works better on BSD operating systems
Savedata management UI

does psp emulator can play psp vita such as Muramasa THe Demon Blade ? Please enlighten my thirsty for game knowledge : ))

Some people really... give 'em an inch and they'll demand the whole nine yards :PPPSSPP can't even run PSX EBoots.The Developers strictly stated that the Emulator will be strictly a PSP emulator.Plus the Vita is a much newer, therefore more powerful, console that'll need to have its own Emulation process developed for it.
