The extensive changelog can be found after the break. Be sure to give it a thorough read for usage instructions and equally important compatibility information.

Changelog

Usage Notes:
1) Before you can use the Advanced Multi-tasking, you’ll need to enable the option “Slim Advanced Multi-tasking” under iR Configurator.
2) You can load 2 Applications to the 2 memory slots in the Slim. Slot 1 is the usual memory area for loading applications (the lower 32MB RAM); while slot 2 is the new memory area (the upper 32MB RAM only available on Slim).
3) By default, the 1st app will be loaded in slot 1, and the 2nd app will load in slot 2 automatically. To force the 1st app to load in slot 2, hold Left-Trigger while lauching an application under the confirmation popup window.
4) The typical app switch toggle “L-Trigger + Select” or the alternate key “Vol Up + Select” will allow you to toggle between the 2 apps and iR Shell. New key combos “L-Trigger + Note” or “Vol Up + Note” will allow you to switch between the 2 apps without going back to iR Shell screen. Pls note pressing the Note button alone (without L-Trigger) will act as the screen capture button. The alternate Vol Up combo keys perform exactly the same as L-Trigger key and is provided as an alternative.
5) Normally, when you exit 1 of the 2 apps, it will cause the PSP to reboot, meaning you’ll also lose the other running app. This can be resolved by adding unloading support into the application itself. However, this will require modification of the app to perform resource cleanup and self-unloading upon exit. All iR Shell bundled plugins have been enhanced to support unloading, such that they can be terminated without affecting the other running app. To exit these plugins gracefully, use the exit function build into the app itself. For example, to exit bookr, press START and choose Exit menu item. iR Shell disables the standard Home exit menu while 2 apps are running. To exit both apps together, use “Home + Square” instead.

Compatibility Notes:
- Not all apps can be loaded to Slot 2. There’re two types of program binary format for PSP, static ELF and relocatable PRX. Static ELF uses fix memory address and can’t be relocated. Hence, they will only work when loading in slot 1. If you try to load a static ELF in slot 2, you’ll get an error code “0x800200D9″. PRX can be loaded in either slot 1 or 2. To convert a homebrew from ELF to PRX, you’ll need to re-compile it with BUILD_PRX=1 and set the heap size with PSP_HEAP_SIZE_KB(-800) in the source file. Most static ELF homebrews can be converted to relocatable PRX simply by recompilation.
- There is a limitation on the PSP AVC hardware decoder which is for video playback. It cannot be accessed by more than 1 application; which means you can’t have 2 applcations running together if both of them access the AVC hardware decoder.
- The bundled plugins should be able to coexist with most other apps; with the exception of the PPA plugin which can only coexist with another app which doesn’t use the AVC hardware decoder.
- You can’t have both slots loading UMD/ISOs, due to there is only 1 physical UMD drive and ISOs are simply emulating the UMD.
- PS1 games take exclusive use on the audio hardware. As a result, it will be incompatible with other apps that use audio.
- The launch XMB function may not be stable for most commercial games due to resource conflicts. However, it should be pretty compatible with most homebrews. On the other hand, the Sony Web Browser should work with most commercial games & homebrews. To browse Internet while running another app, you can use the iR Shell bundled htmlviewer which is the Sony Web browser.
- If an app is built with PSP_LARGE_MEMORY flag and you’re trying to load it in slot 1 (first app), it will use all Slim memory and you won’t be able to load a 2nd app. To allow it to co-exist with other apps, you’ll need to load it in slot 2.
- This will probably be incompatible with DA’s LEDA if you’re trying to run 2 apps requring 2 different kernels.
- This Advanced Multi-tasking feature is incompatible with Interlaced TV Out for slim due to insufficient memory. Progressive TV Out should work fine.
- If you get an error “0x800200D9″ while loading an app to slot 2, it’s a static ELF and you’ll need to load it in slot 1. That is, reverse the order of the 2 applications you’re loading.

Additional Note:
- The bundled bookr plugin is based on the original v0.71. If you want to use the recent v0.81 mod by Nguyen Chi Tam, you can download it from www.ishell.org forum.
- You can find most of the plugin source code in www.irshell.org plugin forum. If you want to add unloading support to a homebrew, you can refer to these samples.

Bug Fixes:
- Fixed most game audio stuttering while mp3 is playing.

iR Shell 4.92 Released [AhMan]

Primarily focused on expanding the application’s already robust feature set, this release introduces support for running PlayStation Network titles within the confines of iR Shell. Additionally, when iR Shell is active, users can now disable MagicGate protection for speeding up access times on non-MG capable Memory Sticks. For the complete changelog, look past the break.

Changelog:

* Support Playstation Network downloable games & demos.
* Interlaced TV support has been added for PSP slim. Games & homebrews launched via iR Shell will inherit the iR Shell TV mode. Most games will run at full speed with default CPU clock.
* For slim PSP TV out, added an option to control the audio output to PSP speaker. This will be useful for docking station with TV out & charging capabilities.
* Added an option to disable Memory Stick MagicGate support. This is meant to be used for PhotoFast microSD to MSPD adapter, or other similar non-MagicGate MS. By disabling the MagicGate support, you will no longer experience the annoying pause in XMB, such as turning on the PSP, switching off USB mode from XMB, quiting game/homebrew back to XMB, entering XMB video directory, etc.
* Added connection timeout support for nethostfs.
* For IR learning remote, added the ability to abort the learning process without waiting for timeout.
* Support user provided font files.
* Plus various bug fixes.

Download iR Shell 4.9

iR Shell 4.9 Released [iR Shell]

New Features for PSP Slim:

- Added support to homebrews that are built with the option PSP_LARGE_MEMORY, that is, to use the extra slim memory. When running these homebrews under iR Shell, they will have access to another 26MB slim RAM. Pls note 2MB of slim RAM is reserved for iR Shell.
- Enhance the HTML Viewer (originally developed by Dark_AleX) to use the extra slim memory. These should help to reduce “Not enough memory” message when accessing larger web contents. The HTML Viewer can be accessed via predefined homebrew #1 icon.

Bug Fixes:

- Some homebrews weren’t correctly recognized by iR Shell and application names were displayed as garbage.
- When setting np9660 mode in iR Configurator, some homebrews failed to launch.
- Launching PS1 games via popsloader wasn’t working properly.
- Copying a large file from ms0: to nethost0: will crash the system.

Note that version 4.8 of iR Shell is supplied as an update only. That means you will need to have the previous 4.7 release installed. Download links for both versions are provided below.

Download iR Shell 4.8 / iR Shell 4.7

iR Shell 4.8 Released [iR Shell]

For the full changelog on version 4.7 of this excellent shell replacement for PSP, hit the break.

* Support Dark_AleX latest 5.00M33-3 CFWs. Users of original 5.00M33 & M33-2 should upgrade to M33-3 to avoid incompatibility issues. The latest Popsloader 5.00 is also supported.
* An Infra-Red learning remote is added for PSP Phat. You no longer need to hunt pronto codes for your appliances. Just point your remote unit at the PSP and it will learn the iR code. It is available under higher firmwares and not fw 1.5 mode. Refer to the Release Note for usage details.
* The nethostfs connection handling has been redesigned to be more robust. However, iR Shell 4.7 and onwards can only connect to the new nethostfs PC server v2.1. Make sure you’ve updated the nethostfs PC server.
* Enhance UMD/ISO game compatibility via nethostfs MAX mode. Most previous failed games will probably work.
* Usbhostfs & nethostfs host redirection under XMB has returned.
* The Adhoc PC connection for nethostfs was broken since fw 3.71. This feature has been brought back for PSP Phat.
* Enhance the HTML Plugin (by Dark_AleX) to allow direct launching of flash games with extension SWF.

Detailed installation and usage instructions can be found in the included readme file.

iR Shell 4.7 Released [iRShell]

Just to let you know I’ll be releasing another iR Shell public release for 5.00M33. It will have all the SE features, including infrared remote learning. Currently, irshell.org is being re-designed and re-worked by some of the private forum members. Once the site is completed, the public release will be out.

A notice on the official iR Shell page informs visitors that the site will be online by next week, so assuming all goes according to plan, we could be looking at a mid-November release.

iR Shell for Custom Firmware 5.00 M33 — Soon… [PSP-Hacks]

irshell/bin/irshell38x.prx: offset 0x284e, 0×82 -> 0×00
irshell/bin/irshell38xs.prx: offset 0x28da, 0×82 -> 0×00

If you don’t think your hex editing skills are up to par, Mov of the iR Shell forums has provided a downloadable ZIP archive of the aforementioned PRX modules. Copy the files inside of the ZIP to the “bin” directory found within the iR Shell folder, hit replace, and you should be good to go.

Even after applying the patch, Mov notes that certain iR Shell functions will not work correctly when on 3.90 M33, so for a fully-functional iR Shell it is advised to stay on 3.80 M33 series firmware.

New Features:

* Added support for 3.80M33-2, M33-4 & M33-5. Pls note M33-1 & M33-3 are not supported due to some technical issues which I’m lazy to resolve.
* Added support for 3.80 Popsloader Version 2. Version 1 isn’t supported.
* The 1.5 Kernel Addon for 3.71M33 & 3.80M33 has caused some incompatibility issues with fw 1.5 iR Shell. This is now resolved.
* Enhance PSP ISO compatability. Previously failed ISOs will probably work in this release.
* For slim only, the nethostfs MAX mode is now compatible with WPA.
* Some older firmware supports have been removed to reduce the distribution archive. This version has support for fw 1.5, 3.10 to 3.80. Also, directories EXTAPP15 & EXTAPP3X have been combined into a single EXTAPP to save space. Each APP# directory has 2 EBOOTs, with EBOOT.PBP for fw 3.x and EBOOT15.PBP for fw 1.5.

Thanks Fadil for the tip!

iR Shell 3.9 Released [AhMan]

However, with that bit of good news comes the bad news. AhMan has decided to take leave of the PSP homebrew scene after this last release. StoneCut further points out that the source code to iR Shell won’t be released, so future updates aren’t looking likely, either.

Here’s what he had to say on the official iR Shell forums:

I would like to inform you that there will indeed be another iR Shell release for 3.80 M33 soon …

However, this will be the FINAL release of iR Shell.

This means: After the next release there will NOT be any more releases. Ever. After that AhMan will be retiring from the scene for good. It should be out in a few days if nothing serious happens during beta testing.

Final Release Coming Up [iR Shell]

Please take note that this release will only work with the bugfixed version of Dark_AleX’s multi-disc popsloader, which is available for download here.

iR Shell 3.81.1 – fix for multi-disc PSX games [iR Shell Forums]

Quick on the fixing, AhMan has just released a maintenance release for iR Shell. For those new to this application, it can be called the swiss-army knife of the PSP. It is a really nifty multi-tasking shell that allows users to run UMD games and homebrew, among many other things, through a unique, user-friendly and appealing menu interface.

If you were having problems loading UMDs from the XMB, then you should definitely update. In general, though, it is usually a good idea to update anyway (unlike when it comes to official firmware from Sony ;)) as Developers don’t like to release things without having reason to.

Remember, if you already have iR Shell 3.8 installed then just download the iR Shell 3.81 Update. Otherwise download the iR Shell 3.81 Full Release.

More details (and a list of bug fixes) can be found after the jump.

Bug Fixes:
* Fixed a critical bug in the iR Shell firmware patch which results in unable to launch UMD in XMB and also causes various incompatibility issues with other homebrew apps & seplugins. Just apply the new patch and all issues will be resolved.
* Fixed a bug in Contect Menu which wouldn’t allow you to choose “Select” or “Start” menu items.

Installation Instructions:
* If you’ve already installed iR Shell 3.8, download iR Shell 3.81 Update which only contains update files. Unzip it and merge to your existing iR Shell installation and apply the new firmware patch.
* If you haven’t installed iR Shell 3.8, download iR Shell 3.81 Full Release which is a complete distribution with all updates included. Then, install as usual, don’t forget to apply the firmware patch.

Notable changes in version 3.7 include full support for custom firmware 3.71 M33 on regular Phat PSPs, enhanced UMD game compatibility, and screen redirection via TyRaNiD’s RemoteJoy.

New Features:

* Added support for M33 3.71 CFW for PSP Phat.
* Screen redirection via Tyranid’s remotejoy. UMD Game compatibility has also been enhanced and save/load dialog boxes will no longer crash. Thanks to Tyranid for making this possible.
* 2 Player PSOne games via usbhostfs/nethostfs keypad direction using 2 PC joysticks/keyboard. Screen redirection via remotejoy is also supported for PSone games.
* Support for M33 popsloader when iR Shell running under M33 3.52 CFW. Only the latest verion popsloader is supported (that is, the one for pops from 3.00 to 3.52). All other previous versions of popsloader won’t work with iR Shell. If you’re running iR Shell under M33 3.71, the “POP Version” setting in iR Configurator is ignored. This is due to popsloader currently doesn’t work with M33 3.71 due to changing NIDs by Sony.
* Support for M33 UMD Video ISO feature under iR Shell File Browser. This will also work with USBHostFS & NETHostFS. Again, for legally owned backups only.
* The number of iR Shell EBOOTs for various firmwares have been consolidated into just 2. One for firmware 1.5, and the other for firmware 2.x/3.x. This should make it earier for users.
* A new autoboot seplugin is introduced to replace the old “irsfw30x.prx”. This plugin will work under all firmware versions, including 3.71.

NOTE: The PSX 2 Player Adhoc is still in alpha & very unstable. It will not be included in this release.

Special Thanks to:

* Dark_AleX/Team M33 for bringing us the incredible custom firmware. Our PSPs won’t be the same without this masterpiece.
* Tyranid and other developers in ps2dev.org for creating the pspsdk. Without their contributions, we don’t even have homebrews on PSP.
