Widescreen support
Will GRRLIB suport widescreen resolution?

Re: Widescreen support
Modifying the guOrtho line in GRRLIB_Start to guOrtho(perspective,0,479,-40,679,0,300); should give you widescreen (I think - can't remember if I also changed anything else anywhere).

Re: Widescreen support
I though it was a limitation of the libogc... but i didn't follow the updates of the libogc recently...

Re: Widescreen support
The first step for GRRLIB would be to use variables instead of the hard coded 640 and 480.

Re: Widescreen support
I will add the widescreen support in a future version of Wii Quizz. I coded a patch for GRRLIB :
Add in GRRLIB.h :
Code:
#include <ogc/conf.h>
Add in GRRLIB.c :
Code:
void GRRLIB_InitVideo () {
f32 yscale;
u32 xfbHeight;
Mtx44 orthographic;
VIDEO_Init();
rmode = VIDEO_GetPreferredMode(NULL);
/* Widescreen patch by CashMan's Productions (http://www.CashMan-Productions.c.la) */
if (CONF_GetAspectRatio() == CONF_ASPECT_16_9)
{
rmode->viWidth = 678;
rmode->viXOrigin = (VI_MAX_WIDTH_NTSC - 678)/2;
}
xfb[0] = (u32 *)MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
xfb[1] = (u32 *)MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
[...]
}

Re: Widescreen support
Variables:
f32 yscale;
u32 xfbHeight;
Mtx44 orthographic;
.. are never used
Why do you call the VIDEO_Init() function? I guess most developers already calls it before calling GRRLIB_InitVideo()
What is the difference when calling VIDEO_Configure (rmode) and not? Noticed you are not doing it anymore.
