Need help loading ISO
Hey everyone,

this is my first time on these forums and the first time I am using this emulator. From what I have read this is the best PS2 emulator there is so I would definitly want to try it out. Smile

I have, however, a small problem loading an .ISO file in my PCSX2 emulator.

Here are the steps I take.

1) I load up pcsx2-r3113.exe

-Usermode selection-
Custom folder: G:\Playstation 2

[x] Use default settings

-Plugins Search Path-
G:\Playstation 2\Plugins
[x] Use default settings

-BIOS Search Path-
G:\Playstation 2\bios
[x] Use default settings

3) The program starts and I get two windows.
The program and the log.

I select ISO from the CDVD menu.
Iso Selector -> Browse...
Then I navigate to the desired .iso file and double click it.

Then I go to the System menu and press: Boot CDVD (full)

Then I always get a new black window with the following statement:
Root directory not found on ISO image.
Name: IsoFS

My logfile reads this:

Don't mount it on virtual drives(such as daemon tools for example). Use the iso selector that is built in on pcsx2. Oh and by the way, use the latest beta r3878.

I have no other .iso programs installed what so ever.
I will update to the latest version, thanks.

Is there any sort of special directory I would need to put these .iso files in?

EDIT: I have updated to the latest version and it supposidly fixed the .iso problem. However, the program is crashing so I cannot tell if it's really working.
Maybe the specs on this system aint good enough so I will try it out on a different pc later.

Cheers for the quick responds Smile

EDIT 2: My system specs on this laptop are

Processor: Intel® Core™2 Duo CPU T9300 @ 2.50GHz 2.50 GHz
Installed memory (RAM): 4.00 GB
System type: 64-bit Operating System

Is this capable of running the emulator?

That log says you're trying to run a file that's inside the game disk, this is the incorrect way to do it.
If you made an ISO image of your game disc you're supposed to select the big ISO (around 4GB for that game), if you simply copied the files from the original disk to your HDD that's also incorrect, you're supposed to make an image file with a program like ImgBurn and then select the big image file with the ISO selector in PCSX2.

Is it capable of running PCSX2? Most likely.
Will it run at playable speeds? That's for you to decide, that CPU should be enough but you didn't say what graphics card you have.

I have a folder with a bunch of .IRX files and one .ISO file, an .CNF and an .78 file.
Therefor, should I burn a DVD and then run it from the DVD instead?

My GPU is an NVidia Quadro FX 570M
Also, it runs DirectX 11.

Thanks for your reply.
Could you please confirm that I have to burn a DVD?

why would you burn a DVD if you already own the game ?
Just run the iso file using the internal iso loader.
how can you obtain all those files ? How did you just create your ISo ?

Never mind.
My original .iso file was misread as a winRAR zipped file format so I unzipped the .iso with winrar.
I went int the properties and it said it was a .iso file format so it should work with that original file intact.

Thank you for all of your responds.
you're welcome.

Next time read the rules before posting.
