 Posted: Tue Apr 27, 2010 1:52 am Post subject: Game Categories - Source Code |
 |
|
I've decided to release the source code of Game Categories for educational purposes. It's licensed under the GPLv3 and I really wish you folks would respect it, and license derivative works under the same license. I'm really not in the mood for a witch-hunt after those who think they can get away with ignoring it. That includes taking structures and so forth from it (they took a long time of reversing and testing to figure out), GPLv3 is the way to go. :)
This is a source code that has had to many overhauls and is no longer the most organised one around, so please don't be to hard on me, although I think I did a pretty good job compared to most of my source codes. It's methods for patching the VSH are at the least a bit odd, so please try the best you can on maintaining compatbility with Game Categories if you ever release something derived from it.
The M33 SDK is thrown inside the 'lib' and 'include' folder in order to make the compilation more universal. Also, the plugin management done in the updater downloaded by Network Update was based on code found here. The appropriate credits for this go out to the M33 Team.
Go ahead and grab it, and don't make me regret releasing it:

Sweety! I was thinking about reversing it...
Many thanks :) |

Thanks for GPL-ing your work :) This gonna be interesting to dwelve into, since I have very little knowledge about VSH :P

thanks for this, have you discovered something else in reversing vsh modules?
for example would you be able to create an homebrew with vsh look and feel, using sony's sceCommonGui, sceCommonUtils and scePaf (or scePafmini that from my tests can be perfectely loaded in game mode)?
vsh modules have been written in c or c++? i think c++ looking at the complexity of structures and pointers that i got reversing some of those modules... but i see that you use c structures like SceContextItem, SceVshItem, SceSysconfItem, SceCallbackItem...

Um, there is VLF library by Dark_Alex. |

Oh, the VSH modules are definitely written in C++. As Game Categories is written in C though, there's good signs of this, for example:
| Code: | | int AddVshItemPatched(void *arg, int topitem, SceVshItem *item) |
The first argument is actually a pointer to the current class, and in C++ this would've been obsolete. There's more signs of them using classes, and what I did in Game Categories by simplifying them to structures was done solely out of lazyness.
I figured out those structures by reversing a number of VSH functions and playing around with the values - and testing, lots, lots of testing. However, they aren't even used to the fullest in Game Categories, simply because I figured out a large part of those structures solely out of curiousity, not for any practical purposes. I've still got plenty information about the VSH in stock, and VSH-wise, Game Categories is just a start. It's just that I've never found a practical use for the information.
About creating homebrew with the same look and feel as the VSH: I haven't invested time in that as VLF is perfectly fine. I did work out the usage of a number of options of these modules though, such as showing a messagebox in VSH-style (/user/main.c should have a function called ShowErrorBox if I recall correctly). |

Did you ever get it working with the Video menu?
Or did you try, and find it not possible?
Something Sony should have implemented from the beginning is folders in the Video menu.

@bubbletune
ok vsh modules are written in c++.
but in order to use vsh look and feel in homebrews we don't need them.
In my opinion modules needed are
common_gui
paf (or pafmini)
common_utils (maybe)
i Think that only paf is written in c++ while the other two are written in c.
paf is required only because it is imported by common_gui and in homebrew i think we only need functions exported by common_gui.
For page layout, texts etc i think we can use custom rco's...
in conclusion i think that in order to create vlf (vsh look and feel =P) homebrews we need to know how to use common_gui and how to create a completely home made, fully customizable rco.
What do you think?
common_gui is written in c? or at least functions exported are in C? (meaning without c++ mangled names).
have some of common_gui nids had ever been cracked?

| Doesn't paf do it's own memory heap allocation/management and provide it's own libc? |

Yes it does, I'm using both of those inside the user module of Game Categories. |

in game_categories.h you have
| Code: |
// Imported from user module: common_gui.prx
int sceVshCommonGuiDisplayContext(void *arg, char *page, char *plane, int width, char *mlist, void *temp1, void *temp2);
|
this is the function used to display the lateral menu right?
well,
i see that you patch the value width and set it to 1.
can you please explain me why and what is that value for?

Indeed, it is used by the code that displays laterals, but just calling that function on it's own doesn't do the job (that function name is made up by me, I don't know the real name). As for patching the 'width' value, that's simply the dimensions of the lateral, the higher you make it the larger the lateral gets. By default it's set to zero but some strings used in Game Categories don't fit that way. If I recall correctly there is another way to patch that, which involves patching one of the values in the RCO. This works just as fine, though. |

so something more must be done in order to make the menu appear? do you know what perhaps?
btw
sceVshCommonGui_D3EC527D is responsible for creating the title bar (arg1 is the icon, arg2 the text, arg3 unk)

Ugh. Well you could always assign a context menu to an icon and call OnXmbContextMenu from vshmain, which is what I always do. But that's in the VSH itself and not inside homebrew. |

yes yes
but maybe i can save some time to discover things that have already been discovered by others.
