The Spark system has become an old system and has not had an update since 2016, it is possible that the emu does not work on it and there is no emu specific to the Spark system, but if you want to try it, you can transfer the emu with the Dcc program to its extension with the Spark system as it then add your server
But this is subject to an experiment only. You can try the versions specific to the Spark devices, which are by the way all dedicated to the system enigma and not the Spark system until you work one of them with you rename the emu with the same name as the Spark system
I have not worked on the Spark system since 2016, when support for it stopped so much that I forgot that the device has this system. I think you should switch to the enigma system because it is the best and the most recent now and
it has great support
Notice
It must be distinguished between these two terms
Spark system
Spark devices
Available emu are currently dedicated to Spark devices For Enigma2 system This can be seen from the path of the emu files, you can find all of them dedicated to the path of files with Enigma system
Good luck
