Problem with loading ISOs

Alright I just recently downgraded my PSP and I can't figure out how to get ISO's to load. I am using custom firmware 3.71 M33. I put the ISO file in the ISO folder in the root but I still don't see the game when I go to play it on the PSP. I've tried setting the psp to 1.50 kernal and the UMD mode to -NO UMD-. I also do have a UMD in the slot. I can run some homebrew programs like PSPtris and that Wario mastermind game (that I don't know how to play). I've tried using UMD loaders but those just showed up as corrupted files and by the way people talk it seems you don't need UMDloaders for custom firmware anyways? Also the game I am trying to play is Guilty Gear Judgement which i downloaded from demonoid.com. Help will be appreciatedd .

Put UMD mode to $0NY NP9660.

I tried that as well but the ISO still doesn't show up in the game menu. Is there a specific place where you access the ISOs or should they be in the same place as the homebrew applications on the PSP not the memory card?

You should've asked

ISO/CSOs go in "ms0://ISO/"

Yeah I made an ISO folder in the root and put the ISO file in there but I'm wondering if you load the ISO on the PSP just like you would load a homebrew program? Do you go to Game then Memory Stick?

I don't know my memory card is all messy after I used the pack generator. I'll upload images.

First time uploading images to a forum post lets see if I do it right...

This is my root folder.


This is my PSP folder.


Is everything there thats suppose to be there? I might have deleted something I shouldn't have is what I am thinking..

Yeah, you just load it up as usual.

all you have to do is drag the .iso into the ISO folder in the root of the memory stick, not in a sub folder or anything.

The ISO file is in there though..... It just doesn't show up on the psp when I look for it. I'm not sure what the problem is or what should I do.

Here is the ISO file in the folder. I'm pretty sure its the right type?


Also, thanks for responding so fast. Was expecting to wait a day at least lol.

IDK, dude... If the ISO is formatted correctly it should show up.

Take a look at the contents of a UMD, and the contents of the ISO.

If the root of the ISO is simular to the UMD's then, maybe its a bad dump.

odds are, assuming you have set up correctly, that you have a bad ISO dump like Roxfox said.

AH I figured it out! I guess the file was extractable.. Lets see if it works

Nevermind I think all the ISO files are like that..... I don't know is there anyway to like defrag the memory card? Also what do you mean by "bad ISO dump"? The ISO is bad or there is something wrong with the memory card?

AH I actually figured it out this time. The ISO file has to be less than 20 characters long. Something so simple got me this frustrated *sigh*.

Well I'm glad you figured it out, but next time please don't double or triple post. Just use the edit button.
