Here is an example source from the Transworld Surf Extractor by me and Bart

nobody replied as of yet?
what a shame! :)
good stuff man! now finally my C knowlegde is going to be put to use! :D

[Trailer Trash]

I'm near the end on my first semester of C++ and I can read some of that. Strange!!

You do any other code?

[bolbort]

:) Thanks snoop buddy :)

What about you make one for Gran Turismo Concept?;) PLEASE!:D

[gmeak]

hey im doin enter the matrix ntsc cd version and i already removed the dvd protection using hex workshop

now i have 2 large .dfu files i need to be opened so i can get in them and make thing smaller then seal it back up can that code above be used?

[psxnomad]

now what exactly does this do?

[darkman1]

i like that guys name^^^^^^^^^^^^^

bounce...bounce...bounce

[KRISHNAMURTI]

HE! HE!...BOUNCE!....HU?....SORRY!...I WONDER IS ANY ONE KNOW HOW TO BURN FROM COMPUTER OR RUN ANY DISK DVD OR MAYBE A CLUE?...........I NEED HELP?

Only saw this post today, quite nifty code.
Maybe i'll start developing some tools also.

Oldskool Obscure C++:

void ps2convert (char original[8])
{
for (int i=0; i<8; i++)
ps2conv[i]=original[ 6 - i + 2*(i%2) ];

ps2conv[8]=''; //maybe not needed
}

Haven't tested it yet, but it *should* work :lol:
