Name: VMMaker-tpr.326 Author: tpr Time: 7 October 2013, 6:20:33.98 pm UUID: c46b8256-3e54-4d34-aac2-5643fddc3bab Ancestors: VMMaker-tpr.325
Fix a single-bit constant error in BitBltSimulation>>copyBits:Fallback: - change 16r3FFF to 16r7FFF to correct tallyIntoMap behaviour for Scratch using BenBlt on the Pi.
