Could some body show me how to dump umd's or point me to the right direction where I can get some info Thanks!

I would also like to know.

look for usbsss on google and dl install into your psp game150 folder and your good to go, launch and dump to your pc, read the readme though

usbsss is a great program for backing up UMD just install like regular homebrew and connect to your pc

you can also use PSPFiler. but you have 2 have quite a big memory stick .2 dump games you just load up the homebrew program and i think you first have 2 change the langusge by pressing circle and change it 2 english, then u just press select and press rip umd. you can just google the program but im not going 2 post it because knowing me something bad will happen. but you will be able to find it very easy. hope this helps

Here's a simple program that dumps UMDs onto the memory stick (not the PC) -
New UMD Dumper v0.2: http://www.psp-hacks.com/file/38

UMD Dumper seems to work a treat, thanks for the suggestions cos I was stuck trying to rip UMD's as well

I would suggest UMD Net Ripper which rips over a wireless connection to a PC, and UMD Dax Dumper, which can rip isos and dax files to a memory stick, wireless network, or through USB.

i didnt think umd dax dumper could dump over to the pc yet....well i was wrong i suppose

i use the umd dumper also. and as for the CSO's, theres a program called UMD GEN, google it
