Fw: easier blit question

make sure those masks correspond to the screen format as well

Actual framebuffer runs at 16bpp (don’t know exact masks, but inside
pFrameBuffer there is 24bpp RGB without alpha, nBpp = 24

what should I put in this case?

actually I succeeded getting something working (most noise lines with some
resemblance of real video) by changing DisplaySurface allocation, but you
are right - there is some problem with buffer structures…

SDL_SetAlpha(FrameSurface, 0, 128);

pass SDL_SRCALPHA in the flags parameter, not zero. it’s documented

will try it, 10x
