Once downloaded open UMDDAXDUMPER02 you will have three folders and two readmes
Open the ‘PSP’ folder then open ‘GAME’ and you will have 2 folders that contain eboots.
Put you psp into usb mode and Extract or copy and paste these folders into the game folder on your psp memory stick(ms0:/PSP/GAME).
You will need files from the folder usbhostfs_psp that you downloaded.Once you get hold of this folder put all the files in it,in the folder without the ‘%’ in the name that you just put in your game folder.
*Exit the usb mode( but keep the usb lead plugged in) and then open the UMDDAXDUMPER02 application then try and start 'dumping'.
Your pc should then make a noise and detect the psp. And the following window should pop up (instead of saying multimedia audio controller it will say ‘psp type b’)
Ignore this window for the moment. Open the file inf-wizard.exe located in libusb-win32-device-bin-0.1.10.1\bin.
An application will open. Click next to start. After you click next the below window appears.
It will show you all the usb devices connected to your pc(shown below). Locate psp type b in the list ( not shown in diagram) click it then click next. A device configuration window will appear. Ignore it and click next.
You will then be prompted to save a .inf file. Save it as 'psp' in the same folder where the infwizard application is located. (libusb-win32-device-bin-0.1.10.1\bin).
The go back to the drivers window you previously ignored (below)
And select ‘install from a specific location’. Click next . then locate the folder where you saved the psp.inf file.(libusb-win32-device-bin-0.1.10.1\bin). Windows will then install the required drivers. ( it will take a few minures so please be patient). Once its completed exit UMDDAXDUMPER02.
Go to the folder called usbhostfs_pc. (That was part of the package with usbhostfs_psp).
Make a folder called ‘ISO’ (must be in capitals) in the usbhostfs_pc folder (this is where your dumped umds are going).
Open the usbhostfs_pc application.
A window will then pop up.
(Keep the application open) then go to your psp and open the UMDDAXDUMPER02 application. Your computer should make a noise similar to before and you should notice the pc application of usbhostfs_pc should say ‘connected to device’. If it doesn’t repeat the process from the point indicated by a ‘*’ in this tutorial.
Look at your psp with the application open and you should see the below screen
The option you have to select is the ‘dump to:’ option.
You have to press left or right and make sure it says dump to usbhostfs:/ISO.
The other options are up to you. Like dump format, compression size ( default is 9, its slower but more effective). And there is no points in splitting the dump so select ‘no split’.
Once you are happy with the settings press start and the dumping begins.
You have to have the usbhostfs_pc application open whenever you dump a UMD.
This should be used to make backups of your games for yourself
