In your screenshot in post #5 is all OK. Emulator is found a keys for SIS channels, but you still have a black screen.
What is with Discovery channels on 4.8 and 0.8. Can you open them, and did you put keys in Softcam.key.
i tried a new clean image and i get this error : ERROR: ioctl(CA_SET_DESCR): Invalid argument
oscam version :
