V1.0 : Never released to the public. Very little functionality. Made to compair only .ROM images for the Coleco. V1.1 : First version released to the public. Tested, and used on Gameboy and Coleco images. Limit of 1,000 bytes. V1.2 : Second version released to one person. Tested with Gameboy, Coleco and Atari 2600 games. Minor bugs exposed. No core revisions, just minor updates. Compair limits extended to 10,000 bytes. Speed increase ever so slightly. I even made the batch file output more attractive. V1.3 : Third version released to the public. 10% speed improvement over version 1.2. Output improved slightly, much more attractive. Minor bug fix over previous version error. Slight core revision.
