To: sdl@libsdl.org From: Staffan Ulfberg <staffan@ulfberg.se> Date: 19 Nov 2005 01:00:48 +0100 Subject: [SDL] New driver for OpenBSD/wscons Hello, I've written an SDL driver for OpenBSD/wscons (console mode, somewhat resembling the functionality of the svga driver for Linux). I use it for playing MAME on my Sharp Zaurus. The alternative is to play under X, which is slower. I asked how to submit the driver a few days ago, and posted a link to the patch in a follow-up, so maybe it was missed? Anyway, the patch is on the web at: http://multivac.fatburen.org/SDL-wscons.patch Comments? Staffan
