[Tuxnes-devel] Trying to add SDL Renderer

[W. M. P. <mi...@fl...>]

I'm trying to add an SDL renderer to tuxnes.  Eventually this will give
us full-screen support and additional platforms for free.

After looking at the X11 renderer code, I concluded that the global
variable fb is a video frame buffer filled by tuxnes's emulator code.
I thought that the following pseudo code would display a NES frame:

Init:
bpp = 8
fbinit ()

Update:
drawimage(PBL)
Memory Copy (SDLbuf, p, 240 * 256)
SDL Display(SDLbuf)

When I implement this, the video displayed looks like static and does
not move.  Even if I had some video parameters wrong, I would expect
the video show some type of motion.

Could someone please describe to me the correct process to retrieve and
display a video frame from the rendering engine?

Thanks.
