Error 80020321 When Lauching an PSP ISO Game

Many PSP users that have a homebrew enabled firmware, like the M33 edition, like to dump the contents of their games from the UMD to the memory card. This will save the file as an ISO, allowing them to backup the games or play them without having to carry any UMD disks around. I do the same thing, but suddenly it stopped working today. I tried to launch “Mind Quiz” to take daily test, but I was greeted with the following error: “The game could not be started. (80020321)”.

After a lot of tinkering, I found my problem. To play any ISO games, you need to have an UMD game disk in your PSP. It does not matter what game it is of. In my case, I was running a little experiment with a UMD video disk that came in my PSP starter pack. After I finished, I forgot to take it out of the PSP. Well, at least I learned that it has to be an UMD game disk, and not a UMD video disk.

If the above solution does not work for you, you might also try to upgrading to the latest M33 firmware. I found that with Dungeon Maker: Hunting Grounds, I had to have version firmware version 3.40 or greater. If this is the case, you might want to check out my M33 upgrading tutorial.

Another way is to use the No-UMD mode that is configurable in the recovery menu, but it is not compatible with all games. To get into this menu, you have to fully shut off your PSP, and turn it on again while holding the R button. When you load the recovery menu, navigate into the Configuration section and select the “UMD Mode” option. Press the X button until you see “currently: M33 driver -NO UMD-“. Navigate back into the opening menu, and exit. This will restart your PSP, and you are ready to roll.

      Many thanls, it worked…!!!
      I spent hours trying to set it up, and many more hours to download the game!!! (by the way, is it always soooo slowww to download a psp torrent game??).

      Well, thx again man! and happy gaming.

      PS: How do i do when I wnat to play a game from the umd, do i have to change it again, or is it automatically??

    i have a psp 2000 model (i don’t know all of the specs yet, as i’m that much of a techy) that was upgraded/modified last week. all of the games uploaded (runs on memory) were working fine until earlier today, as my wife noticed. music is working fine, but the games won’t load. displays an eror message “the game could not be started 80020321”. in case i’d get it fixed when i get home, how’d i know if games i plan to upload in the future won’t be compatible with the new setup?

    Actually my problem is that my psp does NOT run the UMD disk neither is it running my memory stick games. :/
    I am badly PISSED.
    When I try to run the 2nd method. It does NOT show me the BLACK menu. But in the system information it says- 5.00 M33-4.

    Dude, I’m fucked. Help me. Please man.

    Reply on e-mail if you can.

  117. bobby / Aug 29 2010

    Man, you freaking rock. I was crapping bricks there, after following someone else’s advise on youtube. His fix did help to stop the games from freezing though (The 333 change on configuring the cpu).

    I just changed the umd, and it made it so that I couldn’t play psp games. Soo many things to remember on these little handheld devices. It’s insane.

  127. SweO / Oct 8 2010

    Thanks a bunch!
    Another tip if you are using the GEN-D3 is to hold the R-shoulderbutton (which will boot you up into the GEN-meny) go to:

    Configuration -> UMD Mode (currently : Normal – UMD required) and change that by pressing the X button once to:
    UMD Mode (currently: M33 driver – NO UMD -).

    Just a tip if anyone else falters and ends up like a did =)

  128. Chance66 / Nov 13 2010

  136. Busta / Mar 3 2011

    You can change settings under configuration so that no disk is required.

    Step one: Make sure PSP is off.
    Step two: Turn on PSP while holding the R button.
    Step three: Go to configuration.
    Step four: On fifth item on Menu press X to change that no disc is required.
    Step five: Go to Back and press X.
    Step six: Restart PSP and voilà no disk is required and no (80020321) message.

  148. Swappi / Aug 20 2011

    I just altered a setting in the VSH menu and the problem went away. In the VSH menu, change the UMD ISO MODE setting to “SONY NP96…”. I dont know what it does, I guessed and it worked.

    Scrolling up I see someone also solved this problem a similar way but used M33 DRIVER instead. Can anyone clarify what this setting modifies in particular? I am guessing its something to do with the emulated umd driver??

    just press select on your VSH menu, and go to driver. Press m33 driver and you’re done!

    Hi your idea is also working because the same thing happened to me. I thought a lot about this and then i pressed the select button and then changed the UMD ISO MODE INTO M33 DRIVER by pressing the left or right button and now once again i can play the ISO/CSO games without a UMD. Try it, it works.
