In Order To Dump A UMD You Need To Boot Your PSP Normally And Press The "Select" Button At The Main XMB Menu.
A Small Submenu Will Open Up, Now Scroll Down To "USB DEVICE" And Change It To When It Says "UMD" - While Your Here Also Change Your "ISO MODE" To "M33 Driver".
Then Click Scroll Down And Select "Reset Device" And Your PSP Will Reboot.
Now When You Put Your PSP In USB Mode (Or if You Have The Auto USB Detect Mode In 5.00 M33-3 Turned On Then The Next Time You Plug Your PSP Into Your Computer) Put In A Game And Close The UMD Door.
And Your Computer Should Show A Single File Something Like Say: "63823.ISO" Or Something To That Extent.
Now Just Click And Drag That File To Your Desired Folder On Your Computer.
And Rename It To Whatever The Game Is Called. (Making Sure You Leave .iso At The End Of The Filename)
You Can Now Either Copy The RAW ISO Onto Your PSP's Memorystick Into A Folder Called "ISO" (Without The Quotes) Or Compress It First With A Program Like PSP ISO Compressor.

(I Personally Recommend Compressing To A Level 8 Compression Ratio .CSO File)
Hope This Helps
