I'm having problems running the game Monster Hunter Portable 3rd on JPCSP (english patch). When i start the game, I get low frame rates when any action occurs. I have tried to find a problem similar to my own but none of the fixes or suggestions recommended actually work. I also have a problem getting my ps3 controller to work with the emulator. When i'm in the title screen it seems to spasm out until i get in the game and at that point, it has like a 5 or sometimes even 10 second delay before there is any action shown by a button press or movement of the joy stick. Should i use something like joy to keys instead? I heard that it might be better than Motion in joy (I am using Motion in joy atm and the latest version). I am also using the latest version of this JPCSP as well. And also, is there a way for the emulator to support a multiplayer function or is is just not possible? My Specs are:

Core i5 3350p
Asus hd 7790 1gb OC edition
Windows 8 Pro with Media Center x64
8 gigs of ddr3 ram g.skill ripjaws

I have tried the regular japanese version of the game but got the same results
Havent used any other emulator
Only plugin i use is Sonic Stage
I'm using the latest version of JPCSP

* And also, does PPSSPP work the same way as JPCSP? I don't have a psp anymore and just want to know if it works the same way or if i need a psp.
