I found this on www.**********.com:
Hello World! Fanjita has just released the Hello World demo for GTA version 0.1! This is a glitch found in Grand Theft Auto: Liberty City Stories, which enables us to run unsigned code through the gamesave.
Readme:
By Fanjita (www.fanjita.org/psp.html)
Based on work by Jim Paris, psp123 and EdisonCarter
Includes code from abu, toc2rta, groepaz and bitmap1
With support from *******. Be sure to check www.**********.******* for future
progress.
Intro
=====
This is a binary loader for the Grand Theft Auto: Liberty City Stories
savegame exploit, demonstrating a simple application being loaded.
It should be compatible with both EU and US copies of the game, and any
firmware version that can run GTA.
Installation
============
Make sure that you don't have any important saves in the first slot of your
GTA savegames. If you do, then just start GTA, load the first slot, then save
in a new slot.
Then just copy the files from the archive to the following places on
your memory stick (the example assumes that your memory stick drive is "F:"):
HW.BIN => F:\HW.BIN
For US copies of the game:
ULUS10041S0\DATA.BIN => F:\psp\savedata\ULUS10041S0\DATA.BIN
ULUS10041S0\PARAM.SFO => F:\psp\savedata\ULUS10041S0\PARAM.SFO
ULUS10041S0\PIC1.PNG => F:\psp\savedata\ULUS10041S0\PIC1.PNG
ULUS10041S0\icon0.png => F:\psp\savedata\ULUS10041S0\icon0.png
For EU copies of the game:
ULES00151S0\DATA.BIN => F:\psp\savedata\ULES00151S0\DATA.BIN
ULES00151S0\PARAM.SFO => F:\psp\savedata\ULES00151S0\PARAM.SFO
ULES00151S0\PIC1.PNG => F:\psp\savedata\ULES00151S0\PIC1.PNG
ULES00151S0\icon0.png => F:\psp\savedata\ULES00151S0\icon0.png
To Run
======
Just start up GTA, select "load game", and load the 'Hello World' game save.
Shortly after loading starts, your screen should go white, then the Hello
World screen will show.
You can optionally dump debug information about the system state to your
memory card.
Using this loader for other programs
====================================
HW.BIN can be replaced with another program, so long as it obeys these
restrictions:
- Must be linked to load to address 0x09fc0000
- Entry point must be 0x09fc0000
- Your application is responsible for determining its own syscall IDs - the
standard NID stub method for linking with the system will not work.
- Maximum theoretical supported size of 64k - the real maximum may be
somewhat smaller.
Just like the very first Hello world for PSP which ignited the homebrew scene, this demo has shown us a future of homebrew for 2.XX users. The current demo is very basic, but we can expect some great breakthrough very soon.
EDIT: Hmmm didn't know that url wasn't allowed....lol...sorry
