I can't seem to get DJ MAX Portable 2 to work for my PSP. I'll try to explain as best I can.. Firmware history: 2.60 -> 2.71 -> 1.50 -> 3.40OE-A I also reformatted my mem stick before and after each firmware update, and default settings.. no problems with the firmware updates. I can get the game to run by having no-UMD disabled, however this causes the game to crash after 2-3 songs and seems to be a common problem with everyone. The solution seems to be to run the game with no-UMD enabled, but that won't work for me at all, whenever I have no-UMD enabled I get the message: "The game could not be started (80020321)" So basically my no-UMD function doesn't seem to be working when it's enabled.. I saw one person with a similar problem/error message but couldn't find a solution. Here's what I've already tried... -reformatting memory stick, putting only the uncompressed .iso in my ISO folder -deleting config.se in flash1 -resetting to default settings -tried different options in the Advanced->Advanced menu from recovery and I still get the same error message when I try to run no-UMD enabled. anyone have any ideas? should i try to reflash to 1.50 -> 3.40OE-A or to a earlier cfw?
