Date: Mon, 14 Apr 2003 22:08:27 +0100 From: Patrice Mandin Subject: [SDL][PATCH] 2 patches for sdl Here are 2 patches for SDL: - One is to put the dummy video drivers at the end of the video drivers list. It gave me problems, when SDL_VIDEODRIVER is not set, and the dummy driver is used instead of the platform's driver, just because it is always available. So the dummy driver must always be at the end of the list. I suppose picogui and dc video drivers also don't work.
