Can't you get the graphics card to average the pixels for you by downscaling to 1/8th size with filtering and then read the average pixel colour from the reduced sized texture? Even if you have to downscale by 1/2 3 times should be fast...Arcade conversions, automatically convertedHi!

I was saying instead of reading 3 pixels from 8x8 you can just downscale the graphics card will blend colours together and after that you get average from reading 1 pixel. Reading from GPU is slow, but scaling is fast.Detecting flash mode inversionsIs is possible to detect with certainty when flashing characters change from normal to inverted and vice-versa?
