Any DAAD game for Spectrum Next should work with ZEsarUX using the following call from command line, while being at the ZEsarUX folder:
zesarux --noconfigfile --zoom 1 --machine tbblue --realvideo --tbblue-fast-boot-mode --enable-esxdos-handler --nosplash --forceconfirmyes --nowelcomemessage --esxdos-root-dir "<PATH TO THE FOLDER>" --cpuspeed 100 <FULL PATH TO THE TAP FILE>
Where <PATH TO THE FOLDER> is the PATH in your computer where you extrated the file, and <FULL PATH TO THE TAP FILE> is the same path plus the name of the tap file.
If that doesn't work, try copying only the tap file to the ZEsarUX folder, and then <FULL PATH TO THE TAP FILE> is just the tap file name.
