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
