Strange, I think I got it to run now. Not really sure what the problem was before. It closed pretty quick after running through the script. I looked on emulation and don't see any covers or metadata
I scraped mine long time ago and I just keep backups now but from what I can remember to do it from windows I had to first browse from windows networks to the roms folder and map network roms folder...
On line 17 of script you choose what you want to scrape...for 3d boxarts and screenshots you enter
You can also set the paths in the script but I prefer to edit games.xml with notepad after..
Then you go to the roms folder from mapped drive and you place the script in the main roms folder..
Run script and it should download sselph.exe on first run..
when you r asked which system do you want to scrape you enter the name of the roms subfolder ex nes or snes..
and it should start scraping.
