![]() ![]() ![]() The resulting disks should work with the C65 DOS, without modification, at least to the extent of being able to get a directory listing, and load one modest size program from it.Ģ. The disk format should allow creating disks that can be written to using the MEGA65's floppy controller, if that is the user's intention.ģ. For mastering disks for games/software distribution, we don't care about write-ability (at least not on all tracks), but we would really like to be able to cram as much data as possible onto a disk. ![]() By reducing the inter-sector gaps, it is possible to fit more sectors on a track. That's how the Amiga gets 880KB on a DD disk, compared to the 1581's 800KB.Ĥ. We need a common disk image format that can be used for all variants of the above, to ease software development, and make it possible to run these images from SD card. (1) and (2) are the easiest ones to solve. In fact, I have solved them already, by implementing a 2nd parallel MFM decoder in the MEGA65's floppy controller, that runs at 2x the data rate of the main decoder. ![]()
