Date: Mon, 12 Jul 2004 14:17:47 -0500 From: Richard Smith Subject: Re: [SDL] Disableing color depth and mode searching > Also, I should add that a quick way to get the desired effect is to > #define BROKEN_MODES on top of the SDL_fbvideo.c file. > Ah yes, I see that looks like that will do what I need. Curious as to why this is a #define and not an enviroment variable like the other settings. I would think that finding cards (or chips) with broken modes would be the norm rather than the execption.
