Item description:

All of us mourned the news about AhMan stopping development of iRShell. But then, just a little less than a month ago, we discovered that AhMan was still at work improving iRShell to make it even better than it was currently. And personally, I expected nothing less than a knocks-your-socks-off release. The day has come when we can finally lay our hands on the best PSP shell ever released.

And am I impressed? Well, that would be a huge understatement to say the least! AhMan has made the best PSP shell even better, in the only way he can - dumping a truckload of features, and making all of them work great in tandem. Obviously, I haven't had a chance to check out all of the features in there, but just for convenience sake, I'll list them from his documentation:

New Features:

* Added "Mute Game Audio" funtion via R-Trigger+Circle or last menu item. This will bring up an Audio Channel Menu which allows you to mute each individual channel. Example, you can mute the in-game music and leave the sound effect. Pls also note the iR Shell MP3 Player is indicated as "MP3 Player" in the menu and can't be muted.
* Modify the change CPU settings, so that it won't cause system hangup even if a game is running in the background. When you change the CPU speed and a game is in the background, you will see the screen flashes which is normally. Pls also note that the change of CPU speed under devhook environment has been removed, which means you can't change CPU speed within iR Shell when running devhook.
* Allow redirection of PSP keypad to PC Keyboard or PC Joystick via USB or WiFi (usbhostfs or nethostfs). You can, for example, use a Xbox/Xbox360 gamepad with 2 analog sticks to control movement and aim in a FPS, like Syphon Filter. You can choose "Redirect Keypad to Host" via usbhost0, nethost0, both, or No Redirection under iR Configurator.
* Allow pmf movie as splash screen. Use iR Configurator to choose startup splash type, including bitmap file, pmf movie or no splash. The included skins do not include any pmf movies, you'll have to download them separately. The PMF player has been enhanced to support movie clips with resolution lower than 480x272.
* You can now launch 2.71 XMB from iR Shell under firmware 2.71 (Real 2.71, devhook 2.71 or 2.71 mode of SEB"). With host redirection, you can view host video using 2.71 XMB video player, mp4 & avc are all supported. Photo & music redirection won't work. You can also use the built-in iR Shell MP3 player after launching XMB.
* Updated the launch XMB function, so you can leave the game disc in the UMD drive when launching XMB. It will now detect your disc type. If you've a UMD Video disc, it will launch the movie automatically. If it's a UMD Game disc, it will skip the auto-launch and just goes to XMB.
* Allow the use of the 4th brightness setting (maximum) on the LCD. Normally, you can only set the 4th brightness when connected to a power adapter. This version allows you to activate the 4th brightness anytime by pressing "Left Trigger + Brightness". The setting will also carry over to Devhook firmware emulation when iR Shell is active. To return to normal brightness, press "Brightness" button.
* When installing skins, iR Shell will also install "splash.pmf", "logo.bmp" & HELP image files from the skin directory. A default set from /IRSHELL/SYSTEM will be used if any of these are missing in the skin. The logo.bmp is now unprotected, so you can use any 480x272 bitmap file as splash screen. You can skip Help file installation via iR Configurator option "Skip Help Files Installation", this may be useful if you've customised language specific Help files and don't want to be overwritten.

This version includes the following plugins for 2.71 iR Shell which means you can open those file types under firmware 2.71:

* Pmf Player (PMF)
* Bookr 0.71 (TXT & PDF)
* PMPMOD AVC 1.02 (AVC)
* Atrac3 Player (AT3)
* ZIP & RAR Unarchiver (ZIP & RAR)

You can associate an icon image to each sub-folder under APP view. Name your icon image as "icon.png" and place it inside your sub-folder. Example, /PSP/GAME/$Emulators$/icon.png
