psp_game umd_data error code

I already convert the game it into an ISO using UMDgen but when I run on my psp it just gives me this error (the game could not be started(8001*******))

My psp's CFW is 5.00 m33-6

 

Try udpating to GEN-D3 and then to Prometheus v4 and see if that helps.

Or just use this - http://pspslimhacks.com/m33-prometheus-installer-v2-0-released/

 

So what was the game when you got it originally?

And what game is this?

IF this is a ps1 conversion then it won't work.

More info required.

 

i download some games from this website www.gamestorrents.com/eng/
then it come part by part

 

How's the game called?

 

what do you mean what's the game called is it the folder or when i open up the folder?

 

No, what's the title of the game, E.G. Rachet and Clank.

 

I downloaded about 4 games:
Disgaea Ininite [JAP]
Zettai Hero Kaizou Keikaku [JAP]
DJ Max Portable Hot Tunes [MULTI2]
NeoGeo Heroes Ultimate Shooting [JPN]

 

Ok, I hand this over to the other members because I have no idea on how to fix PSP's
