Thanks for the videos, but as said, I already imported other systems without problems, on this while I did with NES and Megadrive ;)
Only platform I'm having issues is snes that I'm getting a blank list...
And it bugs me because I have no issue loading them in hyperspin, that's quite more buggy
Import process is quite straightforward, I don't get wiy the list appears blank...
Edit: BTW they are not 7z, my bad, but zip files ;)
