How to run a CSO file on your PSP

How do I run my CSO files on my psp? I tried using devhook, fastloader v0.7, and DAX. Neither of them would work. I can run ISO's using devhook but I would rather use CSO's since they are smaller.

CSO files work on Devhook. You must be doing something wrong.

CSO files work exactly the same way as ISOs through Devhook....

Well I guess Ill just have to try again. What makes me frustrated is that i can run ISO's fine at 222MHz but when I try to load a CSO the screen just goes blank.....

I managed to get my TekkenDR down to 750mb :)
Edit: Soul187, try renaming the CSO file by putting the small v-letter in the beginning of the name. It has helped me many times :)
example "vSplinterCell.cso"

Did you use the DAX app by any chance? And im trying to run my cso version of Field Commander but its been at the opening loading screen for the past 5min and I got my clock speed at 333. Any idea what may be wrong?

Ive tried a Field Commander.cso on my PSP that didnt boot either. I used Devhook.....not sure if its the file or not.
#13
I haven't used DAX, Imo CSO gives better packing :)
Oh, and also, do you have the EUR/USA version of the Tekken?
Mine is JPN version, got the USA version only down to 799mb :<

EDIT: Hmm, sounds like a bad file to me with that Field Commander, but as I said before, first Try renaming it to "vFieldCommander.cso/.iso" :)

Yeh I do have the English version which must be why. But this is my first Tekken game I actualy got so I'll just stick with the English so I understand it. Yeah and BurnCK I fell your pain. I am about to try Cobspider's idea and ill tell you if it works. And by the way what program do you use for compression Bosspider if you dont mind telling me.

hah, no probs. :)
All the tekken versions I've caught this far, are .cso.. there shouldn't be a problem with them.. Now... What was your DevHook version? :)

Tekken can get down to 787 mb i believe without sacrificing too much. To get it down to this size, the ending movies are relinked, padding is removed, and update folder is deleted. If you are a lazy, use a ripkit, or you can do all the same things using UMD Gen and the tut I made when the Jap version was released. Heres the tut if anybody wants a pretty easy way to shrink Tekken: http://forums.afterdawn.com/thread_view.cfm/362632
