With the capability to fetch from anywhere in memory, perform arbitrary ALU operations and write the results back to memory, in conjunction with the raw floating point performance of the large shader ALU array, the MEMEXPORT facility does have the capability to achieve a wide range of fairly complex and general purpose operations

That shader stuff looks a LOT of C/C++ to me  (IMG:style_emoticons/default/blink.gif) Gotta test some #include <stdio.h> etc. stuff (IMG:style_emoticons/default/biggrin.gif)

EDIT:
Ok, I changed PsAfterEffects.hlsl to

//-----------------------------------------------------------------------------
// After Effects pixel shader
//-----------------------------------------------------------------------------
#include "..\stdio.h"

int main() {print("I love Xbox 360! With regards to Xbox-Scene etc. (IMG:style_emoticons/default/tongue.gif)");}

... but I'm too afraid to test it if it'd break my 360 (IMG:style_emoticons/default/biggrin.gif)
For those brave ones that want to try it, I suggest that you put the stdio.h to the Shaders dir (IMG:style_emoticons/default/biggrin.gif)

That's not going to work.

Yeah, a GPU can't execute normal code (IMG:style_emoticons/default/biggrin.gif)
But it'd be cool if it would work

i dont know if you guys are watching the xbox hacker forums although granted its slow

but the original poster of this info has posted a link to another guys research called AO

take a look if you havent allready http://www.gamedev.no/xbox360_shaders.jsp

 the gpu shares memory with the cpu

 correction....gpu uses all the  memory and doesnt share it with the cpu.cpu has a small  on-die memory

[-Gadget-]

funny that this is a year on more or less to the day ! ...
but i think we are all hopeing that theres just a glimmer of truth here ! .. and lets hope that more info comes to the public soon !

It does seem odd that this is nearly 1 year to the day....

This exploit sounds extremely awsome. Hopefully we can run homebrew in the future.

I do have one comment to make though to all the haters out there. If this was an exploit in the shaders that allowed the running of unsigned code (homebrew), then there would be need for another hack. This disc must be modified in order to run an exploit. That means *gasp* FIRMWARE HACK!!!!! But I think only like 15 people here really think something of the firmware hack huh....?

Completely wrong. Are you making this stuff up as you go along?

1 year since what? The 360 was released in December in the UK. EDIT: Oh the post

A year since the last post
and more then a year since i discovered the shader hole.
i'm glad everything turned out, how it was supposed to be.
