Installation instructions for 3.52 M33:

1. Unzip the irshell360.zip archive to a directory on your PC.

2. Copy /IRSHELL, /PSP & /seplugins to the root directory of your 
   memory stick.

3. On your PSP, go to GAMES -> MEMORY STICK and then launch pspbtncnf 
   patcher. This will allow legally owned Backup ISOs to work with iR 
   Shell. You can delete the patcher after you run it once.

   Please note:
   The patcher will validate your existing pspbtcnf.bin file and make 
   sure it's a correct copy before applying the patch. It will also add 
   a small file called irspatch.prx to your flash. There are some 
   safety measures built in. The patcher shouldn't be able to brick a 
   PSP. However, as with all free software, use it at your own risk.

4. Next, completely turn off your PSP and then turn it on again while 
   holding R-Trigger to enter Recovery Menu in order to to prepare for 
   enabling iR Shell autoboot.

   - Choose "Plugins ->"

   - You'll see "irsfw30x.prx (VSH) (Disabled) listed. Now, choose it 
     to enable this plugin and it will change to (Enabled).

   - Now Exit from Recovery Menu to reboot your PSP.

5. Your PSP will now autostart with iR Shell upon power-on. If you wish 
   you bypass the autostart mechanism at any later point then hold down 
   TRIANGLE when turning on your PSP. 

   You may need to disable UMD autostart in the XMB for the plugin to 
   work correctly.

6. Done :) 

   Read the User Guide and FAQ for more detailed installation and usage 
   instructions for iR Shell.

   Enjoy iR Shell !

Please note:
Should you desire to run iR Shell under a different firmware than CFW 3.52
by Team M33 then please move the "irshell3x" folder from /PSP/GAME352/
to the appropriate GAME folder for your firmware.

If you would like to install iR Shell on any of the older OE firmware you 
will also have to manually apply the patch to the PSP's flash memory 
because the pspbtncnf utility will not work:

Copy /PSP/GAME150/btcnfpatch/irspatch.prx to flash0:/kn/irspatch.prx on
your PSPs flash memory by using recovery menu or pspfiler.

Edit the flash0:/kn/pspbtcnf_game.txt file and add the irspatch.prx to it. 
The entry needs to be added between "$/kd/ata.prx" & "$/kd/umdman.prx":
$/kd/ata.prx
/kd/irspatch.prx
$/kd/umdman.prx
