What steps will reproduce the problem? 1. Download Corpse Party from PSN 2. Transfer to PSP 3. Start game

What is the expected output? What do you see instead? Game should start, but it constantly returns the 80010087 error

What version of the product are you using? On what operating system? 6.20-B10.fix1

Please provide any additional information below. Tried turning off plugins, changing drivers, turning off caching, etc. Nothing seems to work.

working fine on me 6.20 PRO-B10(fix)

Did you install the permanent patch? Are there any settings that I might have to change to get it to run? I'm at a loss as to what it could be.

You need to download and install copies of PSP games DIRECTLY on your PSP. Downloading a copy of a PSN title from anywhere else and dumping it on your PSP WONT work since almost every PSN downloaded title is signed for ONE specific PSP. You can also try some decrypting plugins like nploader or npdecrypter but that might not work.

Um...I explicitly said that I downloaded it directly from PSN (in this case onto my PS3) and then transferred it to my PSP. It's worked many times in the past...

yes i have perma patch installed but i don't think that will affect the games brought from PSN well i downloaded mine using my psp and it work fine

Since you already bought it on PSN simply download it Directly from PSN on your PSP. That should fix the problem - of course if you disabled all additional plugins that might cause this problem.

No, I tried downloading directly to the PSP and it still doesn't work. I also tried downloading to a cleanly formatted memory stick and it also didn't work. I even tried deactivating and reactivating my PSP and that didn't work either. So I'm at a loss as to what it could be unless there is some setting that is making it not work.

after a quick search on Google, it looks like some games just require that you download them from the PSN store using your PSP. obviously, this would probably not be good with CFW. got that info from youtube: watch?v=H29ZINaHlRw

note that I have never had this problem, because I use MediaGo on my computer for downloading from PSN. I did not make the video, either... the only setting I know of that may have an impact is the "NoDRM Engine". access it as:

Recovery Menu -> Advanced -> NoDRM Engine

probably want this enabled.

It's enabled by default and you need that to log on to PSN if you have an older CFW than the current highest (older than 6.60 by today). I dont have problems with PSN since the offer of PSN titles in my country is VERY limited. I got my games mostly on UMD or in *.iso format. The only PSN title I have works fine so far.

last thing that comes to my mind that you scould do is: - Reinstall PRO CFW (to make shure that the instalation is ok and your back to the default settings) - Format your MS - DONT copy anything on your MS after the format (no backuped savegames, no plugins, NOTHING) - Download the game from PSN using your PSP's PSN store. - try to run the game.

If that doesent work - I dont know what will.

Still doesn't seem to work. Now, I did notice something weird. Without CFW running, it asks me to update to 6.60 when I try to start the game. With CFW running and with no version.txt it gives the 80010087 error and nothing about having to update to 6.60. Not sure if that'll help figure out where the problem is...

I'm having the exact same problem with A Space Shooter for 2 Bucks on the same Pro verion. With the CFW, I get the same error you get with Corpse Party. Yet when I switched to OFW, it gave me the 8010850E error. Nothing about updating to 6.60.
