[caizer]

hello, i'm new here..

i downloaded a jpcsp emu & tried it w/ some games i have but it doesn't seem to be working, once i run the game it's just black screen..

i'm sure i have java installed coz i use it too for other emus..

INFO:
Windows XP SP2
Intel Core 2 Duo E7500 2.93Ghz
RAM 2GB

i know the infos are little but i really need some help.. i forgot the video card i'll try to post other details here later..

sorry to bother & thanks in advance..
