from KylBlzL:

A small shell with a windows-like interface, windows-like meaning with a task bar and desktop type environment. features a task bar on the bottom, letting you close and minimize programs.
The lack of memory for the sparta exploit means i included 2 main programs:
-Notepad with a danzeff keyboard
-PSPDraw which is my own design.
Plus addons:
-mouse config sets speed, color, and other attributes
-sys info gets pretty much everything about your psp that is accsessable

Works on all PSP models [Phat 1000, Slim 2000, and Brite 3000] on all OFW up to 5.02. Also, it works on all current M33 firmware [most recent is 5.00 M33 - 6]

New to 0.9b:

Overhauled with SCEIO:
- load/save support of most recent document in both apps
Tweaked UI:
- you can now click DIRECTLY ON THE TEXT ..as well as the actual buttons.
- moved shortcuts ..to be more awesome
- included info/exit buttons ..ftw
- save/load buttons on apps ..so you can actually use those features
- more labels ..so u know wtf your clickin on :D
- new tripple buffer ..for faster awesomeness
- danziff keyboard works and looks better ..because i used pictures of danzeff for more chars
Bugfixes:
- fixed an odd problem with the keyboards second charset
- fixed an error with an odd mouse behavior causing a freeze
- not-so-random code cleanup/optomization *-*-*-*
- made the delay between keypresses shorter **
- fixed a small error in PrintFine that made lables not visible
- now 100% "infinate loop" free! [but screenshot takes a while]

Known Bugs:
- Clock displays wrong times sometimes [if it is, just click HOME/PS and look at the time]
- Load Draw freezes if Ms0:/PHOTO/Draw.bmp is less than (200,200)
- Load Note freezes if Ms0:/Note.txt is greater than 1303 chars or has too many /n

Install:

-Get the gamesave exploit [i cant include it] and put it in MS0:/PSP/SAVEDATA
-Move h.bin to the root of your memstick
-DONE!
