This is mainly a maintenance release with a few bug fixes. It also adds a new feature to support homebrews to use extra slim memory.

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.

Special thanks to:
- Osgeld for spending so much effort in resurrecting irshell.org.
- Dark_AleX for the M33 custom firmwares and his assistance to help adding popsloader support.
- Tyranid and other developers in ps2dev.org for creating the pspsdk.
- Osgeld, StoneCut, F34R and other moderators who keep irshell.org running and providing technical support to the community.
- All iR Shell beta testers, donators, skins & plugin contributors.

- remotejoy & usbhostfs are developed by Tyranid.
- iR Shell bundled skins & plugins are developed by their corresponding authors.
- iR Shell Manual & FAQs are written by StoneCut.

QUOTE:

本次更新版本主要修正了之前版本的一些BUG。同時新版本增加了一項新的特性：支持自制軟件使用PSP 2000系列額外提供的內存。

針對PSP slim新增的功能：

-新增了對部分使用PSP_LARGE_MEMORY特性編譯構建的自制軟件的支持。也就說，irshell 開始支持自制軟件使用PSP slim額外提供的那部分內存。當使用iR Shell運行這類軟件時，這些軟件將可以訪問PSP slim額外提供的26M內存空間。請注意，IR shell將保留2M的內存以保證自身的正常運行。

-改進了HTML瀏覽器（該軟件的原作者是 Dark_AleX)的功能，使其能夠使用psp slim 額外提供的內存。這個改進有助于減少在瀏覽大容量網頁時出現“內存不足”的提示。HTML 瀏覽器可以聽過預定義自制軟件 #1（homebrew #1 ）圖標來啟動。

Bug修正

-修正了某些自制軟件不能被iR Shell正確識別，應用軟件名顯示亂碼的問題
-修正了在iR Shell里設置了np9660免盤模式之后，某些自制軟件無法運行的問題。
-修正了使用popsloader啟動PS1游戲無法正常運行的問題。
-修正了從記憶棒復制大容量文件到nethost時出現的系統死機現象。

特別感謝：
-Osgeld花費了大量精力重新打造了irshell.org網站
- Dark_AleX開發的M33自制固件和他的幫助，使iR Shell能夠支持popsloader
-Tyranid 和ps2dev.org 網站的開發者們。感謝他們創建了pspsdk開發包。
-Osgeld, StoneCut, F34R以及其他管理人員，他們保證了irshell.org網站的正常運營，同時為這個社區提供了技術支持。
-所有ir shell的軟件測試員，支持irshell開發的捐贈者，和為軟件提供皮膚和插件的朋友們。

版權申明：

-M33 自制固件和popsloader 是由Dark_AleX/M33開發的。
- remotejoy & usbhostfs 是由Tyranid.開發的。
- ir shell附帶的皮膚和插件的版權歸屬對應的開發人員和作者。
