- Seperated disk and disk drive emulation - Support more drive types - 5.25" dual RPM, 3.5" DD, 3.5" HD, 3.5" HD 3-Mode - Support drive swapping (FDC37c665 only) - Support FDC FIFO - Support other FDC 'enhanced mode' behaviour - Support IBM XDF format images - Formatting now formats both tracks, and uses correct 'fill' byte - Various other improvements Many of these changes provided by Battler
