GPF posted this news/release:
ok updated my sourcecode on site
http://gpf.dcemu.co.uk/ndsSDL.shtml
added doublebuffering support and fixed some errors that prevent it working with r19 using the new arm-eabi-gcc.
unfortunetly now doublebuffering is on all the time and it uses 1mb of system memory.
in video/nds/SDL_ndsvideo.c NDS_SetVideoMode function this enabled the doublebuffering
change to
to disable doublebuffering and recompile the lib.
if someone has a fix to this let me know. I thought that the NDS_AllocHWSurface(...) would be called and i used to have the malloc defined in there but for a couple of SDL ports they were never calling that function so i moved it into the NDS_SetVideoMode function.
Also a lot of work need to be done to allocated VRAM better, right now 8bit video uses a mode6 1024X512 background
and 16bit video uses mode5 515X512 background. So if you using a smaller screen it shouldnt need to allocate so much VRAM and the doublebuffering memory could be moved into VRAM instead of main ram.
