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
