Save our floppy!
D-Bug's TDE is a program used to convert old floppies into MSA disk images. I know there are excellent apps already out like Jay MSA and Magic Shadow Archiver but TDE works at a technically lower level and therefore has more success with those crusty old floppies. In fact, even if TDE fails with a dead part of a disk, it still offers you the option to save a good image thus you're able to rescue the remainder. Such an excellent and essential utility!
Update October 2020Version v1.05 is now out and with lots of changes: low RAM reqs, low-level FDC code, faster code, Drive B support and is compatible with all Atari computers. See the readme file within the download.
