iPod Linux framebuffer support. --ryan. Date: Sun, 19 Jun 2005 15:53:22 -0700 From: Joshua Oreman <oremanj@gmail.com> To: sdl@libsdl.org Subject: [SDL] [PATCH] iPod framebuffer video driver Hi SDL-list, I've been working on a port of SDL to iPodLinux (http://www.ipodlinux.org). I've created a patch for both the standard 2-bit iPod screen (using an unchangeable palette) and the 16-bit iPod photo. The patch is attached, against version 1.2.8. I've created two pages on the iPodLinux wiki about this patch: http://www.ipodlinux.org/Building_SDL and http://www.ipodlinux.org/SDL_Programming. See those pages if you're curious. Comments? Questions? Is this something that might be able to get into SDL 1.2.9? Thanks for your feedback! -- Josh
