 Doing the same thing from a windows system do not crash the board.
 
 #### Reason

+ ### 3 - Replay may not give the exact same output as final image
+ 
+#### Explanation
+Some of the replay do not output the exact same image as the stored image. This can also happen with user generated contents.
+
+#### Reason
+Probably due to some bugs in previous version, or the Pixel overflow bug, the replay file may not generate the same output as the final image.
+It is most likley due to the pixel overflow bug and some change in the format while development.
+
+It is quite unlikely a fix can be done as in case of the pixel tool overflow there is dataloss.
+Also the official smartphone app and the board show the same problem as the tools provided here.
