ZZogl -- Zero GS KOSMOS fork

[Bositman]

ZeroGS has not been touched in years so the one you had is still the latest. Except if you mean ZZOgl

[abdo123]

ZeroGS it is
it is quite disappointing that it is been dumped

hi there, if there a way to fix the problem in god of war 2 about the lights not doing alpha well or whatever, and instead of doing tranparency with the 3D, it does with the 2D background hence cutting the scene? (tried every hack with no success)

the only way to make it "almost" playable is to activate alpha hack with F9 during the game (activating with the menu doesn't work) but still affected in some points like when figthing the colussus to the get the sword.

background above the 3D (problems with Z axis?)



edit: forgot, i'm ussing linux x86 and fglrx 11.4

hi, i found a problem with zzogl and the nvidia 270.41.06 linux driver with a gf7800gtx.
http://code.google.com/p/pcsx2/source/br...te.cpp#381
glGetStringi = (PFNGLGETSTRINGIPROC)wglGetProcAddress("glGetStringi");
return a nonzero value but
glGetIntegerv(GL_NUM_EXTENSIONS, &max_ext);
fails (i guess as there is no opengl3 context?) so it ends up finding 0 extension

@laharl2k, I do not think anyone is improving zzogl for the moment.

@CME, first upgrade you drivers. I will check the context stuff with SDL code

this is the latest driver

and maybe just put the glGetIntegerv(GL_NUM_EXTENSIONS, &max_ext); before the if statement and check if max_ext is not 0? :V

[gregory]

maybe downgrade it

Yes that was my first idea. But it would be better to properly create a 3.0 context. Maybe it can solve some issue in GLSL too.

CME,
I commit a patch to properly create an opengl 3.0 context. Can you check out the branch and tell me if it works fine. If you have still the same error, I will change the if statement.

Code:

svn co http://pcsx2.googlecode.com/svn/branches/linux-gsopen2

Note, you must take both plugins and pcsx2 from this branch.

it fails to compile with

but changing the line with the error to

Code:

it will compile fine... but it fails with

[gregory]

Ah completey forgot about CALLBACK/EXPORT interface.

ZZogl-PG: No Direct Rendering possible!

Anyway, in this case it failed to get a proper context. Did you have a similar issue with the trunk. If yes, check direct rendering in glxinfo (you must take the 32bits version on 64bits system)
