 ====== Hacking Pictochat (maybe) ======
+===== Details =====
+==== Image format ====
+The drawable canvas is 228x79 (the lines are 16px apart, and there are 5 horizontal segments). You can't draw on the leftmost, rightmost and topmost line of pixels so the actual canvas is 230x80 for a total of 18,400px for a full frame (3680px per "segment")
+The image format (present guess) is 4 bits per pixel for a total of 16 colours - then each segment is 1840 bytes, the full frame is 9200 bytes.
 ===== Capture =====
