  • myself10

    wwe 2011 is not working.. my psp hangs up and turn the screen into black whenever i start the game.. i still have to change the ISO mode from m33 driver/sony NP9660 to OE isofs on the vsh menu to be able to play wwe… on 5.50 gen d3, wwe can be played without changing the ISO mode.. i went back to gen d3… Ü

  • Mr. Gamer

    This thing is cruddy as hell. No offense to the person/people who spent time on it but it’s terrible. Reasons being? Examples of older games not working – Smackdown! vs RAW 2006, Midevil Resurrection, Tony Hawk’s Underground 2 Remix, and Lumines. And for new/newer games? Issues with Kingdom Hearts, Smackdown! vs RAW 2010 & 2011, and I’ve had UFC freeze a handful of times. And all of the aforementioned new games worked on 5.50 Gen-D3! This is garbage – point blank.

    smackdown raw 2011 is workig fine on me…

  • spiceonpsn

  • gennaro494

    I tried this on both of my CFW psp 1000′s…and got error..i had Promo 2 in them so figured why not upgrade to promo 3…guess what don’t! like i said got error..so went to system to check..it now said Promo 3..so i tried GOW Sparta again..and nothing! just stayed black..had to remove battery to shut off..so luckily i loaded Promo 2 again and that installed fine and now everything works great again..
    So if you not having any problems with Promo 2…stay with it.

  • blvicious

    help can someone pls give me the steps to put the cwf on my psp from computer pls or send me a video

    • pspfortress

      If you have this: hackable psp, pandora battery and magic memory stick then proceed .
      >> download the guide on how install cfw on your psp if you want to do it yourself but too risky for you. lol

  • gennaro494

    Blvicious…NO..
    look around or look on Craigslist..they have tons of people on there that will do it for like 10 bucks..
    if you have a 2000 or 1000 psp…
