Fresh out of retirement is AhMan with a new version of iR Shell — the #1 shell replacement for your PSP. Best of all it now supports FW 1.50, 2.71 w/ HEN D, and Dark_AleX’s 2.71 SE-C! Aside from that, iR Shell v3.0 comes fully equipped with a huge changelog; you certainly won’t be disappointed:

• 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. There are total of 8 audio channels on the PSP (0 - 7). Games normally use a few channels to output music, voice & various sound effects. The Audio Channel Menu will tell you what channels the game currently use and you can mute each channel manually. You may need to test muting different channels a few time to find out which exactly channel you want to mute. Example, you may want to 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. You can also control the “Mute Game Audio Type” under Configurator. By default, the muting of game audio will only take effect if the mp3 song is currently playing or paused. If the playback of your mp3 has completed, the muting of game audio will be canceled. You can also optionally choose to mute game audio even no mp3 is playing.
• 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. Devhook itself won’t allow any apps to change the CPU speed while the app/game has been launched. To change the CPU speed in devhook, you’ll need to do it under XMB via vshex.prx. You can can also change the cpu speed in iR Shell under SEB” and then use the build-in devhook launcher, devhook will then be launched with the CPU speed carry over from iR Shell.
• 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. No more awkward control with PSP buttons for aiming. 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 480×272. Previously, these movies can’t be played. A new option named “PMF Movie Scaling” has been added to iR Configurator to scale the low resolution movie to full screen. Default is scaling enable. The scaling option only applys for PMF Plugin. The pmf splash feature doesn’t support scaling option.

There are many other additions — select plugins can now be loaded under 2.71, bug fixes, etc… You can check “Revision History.txt” for more details on those. Otherwise you should probably consider reading the included PDF User Guide for everything else you need to know.

Tremendous work AhMan — good to see you back!
