Delete the SNEmulDS config file and try again. It should work now. Update: @Coto completed his custom DS toolchain. Setting up the toolkit enviroment is required to compile the latest master! You will find the files and the instruction on the githubpage. Update: 09/29/2017 Another Update on the Githubpage. I got the Toolchain up and running. Cotodevil said he will create an Wizard installer for the toolchain sometime later.
