Metal Gear Solid: Peace Walker

[jedi pawn]

I got ppsspp from the playstore and peace walker always crashes when installing the data around the beginning, first time it kept saying its not responding and gave the options to force close, wait or report, on which i waited multiple times before force closing.
Using android ginger bread on sony xperia neo V. Any help will be welcome I'm new to this emulator stuff, and while I'm kindof towards the web developement side, I don't really know c++ so less chinese please

Edit: It turned out I needed a phone restart, but it works too slow I even turned off all graphic settings (even the ones i didn't know, i just unchecked everything) and got that sound plugin but still really slow do you need a controller to enjoy it on the pc? or is it playable without a controller?

pc specs: windows 7, 4 gb ram, some built in intel graphics card, dual core 1.8ghz (it should work fine on that right?)
