Now, we need to get IRShell installed, and a few additional files need to be placed.
I am not going to write a tutorial for installing IRShell. AhMan did a very good job of explaining how to install it, and a spectacular job designing the software. I'm also going to give credit to StoneCut, for his constant assistance to everyone with issues involving the software. These guys make an awesome team. More credits will ensue, but I figured before I get into the software I would go ahead and handle this part of it. Now.... onto the setup

1. Go ahead and download the file at the bottom of the page, it's going to have everything you need for the rest.
2. Unpack the file using WinRar, and send it to the PC
3. Install IrShell 3.6, the folder is called pspirshell36, leave the other IRSHELL folder alone for now
4. After installing IrShell, copy the IRSHELL folder from the download into the root of your MS
5. If your not in Irshell with a 3.52 at the top of the screen, you need to get there for the next part
6. In Irshell, scroll down to the IR configurator at the bottom, and hit X twice
7. Make sure your settings look like these:
Non-MS Media Access: Enable
Redirect APP View to Host: Enable
Redirect Keypad to Host: via Nethost0
XMB Network for Nethost: *Select your network that you put into XMB here*
NetHost IP/Name: mine is blank, you can have something here if you use APs
Nethost IP Adhoc: *Put in the IP address of your computer here*
Nethost Port: 7513
NetHost Password: *Set this to what you want to, but if you don't use mypass, your going to need to change a file later, it's up to you*
Nethost/UMD Compatibility: Maximum
Allow Adhoc PC connection for Homebrew: Enable
8. Now, go back to your pc, and move the NetHost folder to where you want it to go
9. After you move it, if you changed the password for nethost, you need to right-click the nethost.bat file and click edit
10. Where you see "mypass", replace it with the password you set.... if you did
11. Save the file, close the document, and run the file.
12. Make sure your WLAN switch is set to on for the PSP
13. Now, go back to the PSP, and try to toggle nethost. It won't go through
14. Set the WLAN toggle to off, and try again... still no dice, right?
15. Set it to on again, and try to connect one more time. It should connect this time.
As of now, I am having trouble streaming ISO files via the Nethost, but am working on using some other applications to assist with the issue. Now, there are other guides out there on the Net, and I found quite a few, but none of them were concise, to the point, or even had the same configuration. This method worked for me, and should work for you also. If you run into any problems, please post here with the issue and I will try to help you out as much as possible.
Now, for the props:
Dark_Alex - Do I need to say more? A PSP modding legend... if you don't know about DAX, your running Sony Official FW
AhMan - Thank you for all that you have done with IrShell, and for coming out of retirement for this newest release. You have made a lot of things possible!
TyRaNiD - some of the files used in this are from PSPLink, TyRaNiD's creation. Thank you for the materials
StoneCut - The voice of IrShell, StoneCut devoted countless hours to absolving issues with the Shell, thank you for your dedication!
Team M33 - Without them, the FW movement may have come to a halt. They are taking care of us now, and are very on top of things.
I feel like I'm missing someone here, but I can't put my finger on it. If someone knows, please drop me a line so that they can be included in this. Thx
Have fun with this setup, and as always, strive for more than what you have.... push the limits!
Peace,
Vamp
