| If you are writing/stealing code like this, then you definitely should not be messing with your firmware. |

I am not sure I understood correctly, but it seems there are some people here who really want to kill homebrew psp development.

I just wanted to make available a working sample. Yoshi's code doesnt compile, dot's didnt work, and with those two and some help from others we made a working sample people can use...
And this isnt here to "kill homebrew psp development" it's to help it. Granted some people may attempt some not so great applications that cause damage but it's still a tool that should be made available. If a person is stupid enough to use it then they deserve a brick as I did.
Thanks,
PyroSama |

i HIGHLY do not recommend
anyone to attempt any of these
sample code snippets...they are
guaranteed psp brick ...if that is what
you want then have a blast ;)
but dont start crying if not and
dont say you havent been warned

There is an error in both samples:
CopyExecute("ms0:/system_pluging_bg.rco","flash0:/vsh/resource/system_plugin_bg.rco");
"system_pluging.rco"? |

well you really shouldnt follow these verbatim
the correct path is indeed flash0:/vsh/resource/system_plugin_bg.rco
but you shouldnt have to mess with that file
in fact DO NOT mess around with that file
its basically useless and only affects the wavy lines
in xmb menu of psp

I was pointing out the spelling of 'plugin', not the file path.
The error would result in a definite brick with the first example without checking because the file spelled 'pluging'would not be found.
That whole first example should be edited out of this forum, it is a VIRUS.
I am messing with other flash0 files using similar example code.
I know the risks, have bricked two PSPs. |

it is not a virus ...no such things exist for a psp
and dont let anyone tell you otherwise
what you see above is highly incorrect code in C
shoot its not even code at all :P...its like when kids
have paint ...they have blue and red and yellow
and then they just mix around with their hands ..making a mess
and yes that typo would result in a brick ...which
is why mostly anyone will tell you to not look at
this thread any longer ;)

Ok, I guess you got me.
There's no way for any PSP program to perpetuate itself.
Do you have an example of a text (debug or graphics) menu that
you'd share with a C beginner? or a link to find one that can easily be
seperated from the rest of it's program?
Cheers, Art. |

I read correctly if the third poster said that the second poster wants to kill homebrew development.
There is some homebrew that has been shoved to my attention that uses
the first example, and one of them is a real screamer.
It seems this piece of work does find a way to perpetuate itself :p |

you are the one who perpetuated it :P
this thread should not have been revived
frankly it should be locked already as
theres no more knowledge to gain from just
talking ...flash access is very common thing
these days now
