Thanks Roman. Unfortunately I have 2 questions yet.
1) Some baddump roms is appeared in the scan results window with black colour while others with light blue.
What is it mean?
2) Also I haven't only one rom "Sport Fishing 2" but the program appears
Missing Roms: 2 of 68031.
The second rom isn't appeard in the scan results window.
What can I do for this?

Thanks,
bk1.
