The Mac and Windows versions have been updated to 3.0.1, because CPCemu did not start on most Windows 11 machines. Besides, the setup of the Dobbertin HD20 was flawed. The file for the virtual harddisk was created in the executable directory (which, depending on its location, failed due to lack of write permissions). The new version uses (as originally intended) the folder where cpcemu.cfg is located ("%APPDATA%CPCemu" in Windows and "Library/Application Support/CPCemu" in MacOS). The virtual HD20 file will be automatically created the first time the HD20 is used (for which the X-DDOS ROM needs to be loaded, e. g. as ROM 5).
