Am I correct that early (1990s) UAE invented the ADF format? I do wonder why DMS wasn't chosen as the emulated disk image format way back then...
I think format has existed long before emulators, but I'm not sure if it was called as ADF back then. It's just direct image of the disk without anything fancy.
BTW. DMS does work with emulators too. At least E-UAE accepts them as well as ADF. Haven't tried with WinUAE, but I guess it goes with all incarnations...
