[hdeki13]

Hi, im new to the jpcsp and i would like some help on running the game

I have the game up and running and the first few scenes(videos) play extremely smooth, but after those few scenes, the video lags so much and i am not able to move around after the videos.

i have a intel i5-450M processor(2.4GHz)
4 Gm DDR3 Memory
windows 7 64bit

can anyone give me advise on making the game playable for my computer?
