A new version of Atari800DC has been released, here’s the the latest info about it:

[i]Now directory browsing on the CD is supported. Also one can insert a new CD while the emulator is running.
Caution: Due to additional CD accesses needed for this, don’t populate a directory with more than a few hundred files, otherwise entering the directory will become very slow.[/i]

You can download the binaries & source from Christian Goessler’s site & you can also get the binaries from atari800dc-0.65-bin.tar.gz”>here. Thanks to pavelbure for posting this news in this forum topic.
