For reproducing the EMBA user-mode emulation mechanism, the following commands could be used as starting point:

 - Start EMBA docker container with the firmware directory as log directory:
      # EMBA="." FIRMWARE="/home/runner/work/emba/emba/DIR-600_fw_revb5_214b01_ALL_de_20130122.zip" LOG="/absolute/path/to/EMBA/log/directory" docker-compose run emba

 - Change your working directory to the root directory of your firmware:
      # cd /logs/s115_usermode_emulator/firmware/unblob_extracted/firmware_extract/DIR-600_fw_revb5_214b01_ALL_de_20130122/dir600b_v2.14_d1mg.bin_extract/1179788-3612812.squashfs_v4_le_extract

 - Copy the static compiled user-mode emulator to your current working directory
      # cp $(which qemu-mipsel) .

 - Start the emulation with the following command: 
      # jchroot  . -- ./qemu-mipsel ./usr/sbin/hostapd <parameters like -v or --help>

WARNING: EMBA is doing some more magic in the background. Probably it is not that easy, but give it a try.
