Hires-Master v1.0 - This is a an extension to the Commodore 64 BASIC 2.0 that adds some graphics commands.  Originally I thought this came from a disk magazine called Commodisk, in particular issue #35, but that doesn't seem to be the case.  I don't have any information on this extension, but there is a demo program on the disk that you can examine to see some of the new commands.
