Scraping Question - Can I Do It Again But Now with Hi-Res?

[Foldi84]

I have 5 systems and using NBBA theme. I like it but I'd love for the images to be higher resolution.

Can I re-run the Steven Selph's Scraper with "Thumbnails Only" turned off without any harm to my system?

What I mean by "harm" is that I made a couple of changes to a couple of gamelists files. I would rather not lose them and I REALLY don't want anything weird like duplicate content.

What's the best way to do this?
How much room do you think I would need (anyone done this before)? I'd be doing it for 2600, 7800, NES, SNES, SMS & Genesis. I have a 32GB card and Pi is telling me I have about 20GB left.

Thank You All!

There isn't a way to have it only download images but you can backup those and restore them afterward. The process would look something like this assuming the system is nes. The command is long, you'll have to scroll.

cp ~/.emulationstation/gamelists/nes/gamelist.xml ~/nes-gamelist.xml
rm ~/.emulationstation/downloaded_images/nes/*
/opt/retropie/supplementary/scraper/scraper -rom_dir ~/RetroPie/roms/nes -image_path ~/.emulationstation/downloaded_images/nes -image_dir ~/.emulationstation/downloaded_images/nes -max_width 0 -no_thumb -workers 4 -img_workers 2
cp ~/nes-gamelist.xml ~/.emulationstation/gamelists/nes/gamelist.xml

oops I had -width instead of max_width in my original post. I updated it.
