I recently downloaded wwe smackdown vs raw 08 from kiss of deaths post, however when i try to run the game i begins to load up then the screen goes black and nothing happens. anyone else had this problem?? anyone know how to fix it??

I'm yet to try the game myself but you can try setting the PSP CPU speed to 333mhz in the Recovery Settings and try to load the game again.

thanks i tried that but i didn't work, I am using firmware 3.40oe-a will that make any difference??

I have finish downloading the game and it loads in my 3.52 M33-4 FW, it seems that the game needs higher FW to load rather than 3.4, guess you need to upgrade in order to play the game then.
