cso's go into ISO folder. Are you only having problems with cso or all games in general? Keep in mind, certain games can only be run in ISO, not CSO.

#1: 2.81 -> 3.03 -> 3.11 DoH (no more :D)
#2: 1.00 -> 1.5 -> 3.03oe-c
#3: Ceramic white 1.5 -> 3.03oe-c -> 3.40oe
Whatever happens, happens...

hi everyone,
I downgrade my psp from 2.80 to 1.5 succefully then inustall DevHood_0.45 and put the cso file in ISO folder but when I tried to open the file in the psp it say correpted file so now I can't use it.
Any idea how to make it work or is there any other program I can use instead of DevHook to play *.cso files?

i was in your shoes not to long ago, but what you need to do is instead of using dev hook just upgrade your 1.5 to either a 3.04oe-a, or any of the m33 new firmware, no matter wich one you upgrade to, all you need to do once your on one of these firmwares is just format your memory card and then connenct your psp to your pc and in the root of your memory card there will be a iso folder there where you can put your games!!!

Alrite guys! Im looking for sum help and would REALLY appreciate it if sum 1 could!

I have installed every dev hook and emulator i could find and none of them will load my cso's. I have all the rite folders and have a umd inside, ive put the games in an iso folder and dowgraded to 1.50.

I have dev hook 0.6, 0.22, fastloader, mph loader 1.1, emulator 0.8c and none of them will load my games!

They either crash, send me bck to the setting menu or start the umd. If n e one has a clue i would be really grateful.

p.s- would it b better to use m33? would tht do the trick?

games i have been trying are Free Running and Call of Duty Road to Victory.

Upgrade to m33, place iso/cso in the ISO folder.

#1: 2.81 -> 3.03 -> 3.11 DoH (no more :D)
#2: 1.00 -> 1.5 -> 3.03oe-c

@bowser19,

most likely you'll have to upgrade to custom firmware. naruto probably has a firmware update to 3.30 or higher. devhook can't emulate that high, so the only way is to go custom firmware.

ps2: v7 scph-39001 - independence exploit - hdloader 0.8c - maxtor 300gb hdd
(+[__]%) psp slim ta-085v1: 6.60 PRO B10

got a whole lot more to list . . .

you need to enable no umd mode.

-turn off the psp fully
-turn on the psp while holding r trigger
-under configuration, change umd mode to sony np9660 -no umd-

exit the recovery menu, and try the game again

DevHook is outdated. So much easier and more stable using custom firmware.
