[fly824]

ok first i hope this is is the right place. now i am trying to dump my umds to my memory stick using umd dumper 0.1.2 and when i try to dump i get an error message saying: There was an error starting the dump. Check you filename is valid and your UMD is clean the try again. i have tried w/ 4 different games and it happens on each on. what can i do? is there a different program i can use?

Also im using a slim psp w/ 4.01 m33 update 4

Do not use a dumper, there is a UMD dumper built into the custom firmware. Press select select and the VSH menu will come up, scroll down to USB Device, it should be set to memory stick. Change it with the Left or right D pad button to UMD. exit out and go to USB connection and connect to the PC. Open up win explorer and when you click on your PSP drive there will be a funny named iso file. That is your game, Drag it to your desktop and it will dump it there. After it gets finished rename it to whatever you wish leaving the iso extension.

This is the one that I prefer UMDGen 4.0: [Only registered and activated users can see links. ]

It's pretty easy to use with not much hassle at all. Post back and I can help you with it. You can remove the updates and padded cells to get it even smaller with it.

Download and install UMDGen.

After you get the ISO dump open up UMDGen and click open. Locate your ISO that you just dumped and select it to open in UMDGen. Go to the UMD Properties tab, at the bottom left of the screen there is a button that says optimize, press it(this will remove the update file and spme padding files in the ISO). Next click Save and select the Compressed(*.cso) option. This will compress the ISO to CSO when complete. Take the CSO and copy to the (psp drive letter):\ISO folder. The game will now play from the Game menu.

You do not extract the ISO or rar or zip it. The ISO has to be compressed to CSO format(using a UMD compression utility) for it to work.

While on the XMB press the SELECT button, a semi-transparent menu will come up(VSH Menu) scroll down to UMD ISO Mode and select either the Sony NP9660 or m33 Driver by pressing either the left or right D pad buttons, then exit out. The game should play now.

You have to play with that different games work on different ones. If you run into one that is troublesome, place any UMD disk in the drive and the game iso should run then.
