hey... simple answer is no... umd dumper will store the umb file as an iso.. but without the CFW (customer firmware) you cant actually play the game..
its probably easier just to install the CFW, will save you a lot of time and effort

Hacked psps have a different registry that allows them to show and play ISO games found in the root of it's memory (ms0:/iso/game.iso). Whereas a OFW PSP Won't even show the Iso Game, but can only play copyrighted games found in the directory "ms0:/psp/game/ulus10391*/EBOOT.PBP" (excluding the "*") games only. However, hacked psps also have the ability to play these types of games, and more including but not limited to: Applications**, Iso games, and CFW updates
*this is an example of a game directory.
** Applications include but not limited to: PSPwrite, IvEr psp, PSP Maps, UMD Game Dumper, and a lot more
Recently you can not make your psp with a custom firmware with out Pandora, Think about buying a Pandora battery on eBay, they are cheap.
Make or buy a pandoras battery
Cause you need to make you PSP Go To the lowest firmware (kinda like downgrade) Then you can install you custom firmware
If you have official firmware you can only play demos If you have Custom firmware you can play all kinds of games So You Don't have custom firmware
u cant now to answer your question. you can but you have to have custom firmware and you have to download this program but i dont know what its called
IF you mean by dark _alex's custom firmware... he said he is not going to make anymore. So either find another homebrew which is NOT M33 eg HX or hopefully he will be pursueaded by everyones concerns. HOpe that helped that may be true but there are hackers and developers other than dark alex. If he wont make a new one, someone else will. Expect it later in the future but for now just work with 4.01 m33-2, that is currently the most advanced CFW or custom firmware.
your only option would be to go to Mexico and replace the software with a PC like software wich is illegal in the us but not if done in Mexico...
ISO and CSO (compressed ISO) can only be played on CFW (custom firmware) or (i think) version 1.50 official firmware. You CANNOT downgrade to an earlier custom firmware or software sit until a newer custom firmware is available. You will have to make a Pandora Battery and a Magic Memory Stick. Basically you have to open up a PSP battery and cut a certain peg. The magic memory stick is alot easier and doesn't pose a threat to the PSP. Watch a tutorial on youtube for the Pandora Battery so you don't stuff up, there is a different method for the PSP Slim battery and the PSP Phat one.
use a Pandora battery and a magic duoo mem stick you can make them both or you can buy them or get someone over the internet to mod it for you but i don't trrust them me
You need yo make a Pandora's Battery and Magic Memory Stick. But you will also need to have (or borrow from a friend) a psp with custom firmware. Heres a link on how to make both. http://wiki.answers.com/Q/How_do_you_make_a_pandora's_battery
you can only go from 3.72 official firmware to 3.90 custom by using a Pandora battery to downgrade your psp to 1.5 then upgrade to 3.90. to obtain a Pandora battery you cam buy one from eBay or if you know someone on custom firmware, they can make one. (WARNING, once your psp battery has been turned into a Pandora battery it can't be used as a normal battery)
You can update your graphics cards firmware and software,but there's not much else without upgrading.
