@toughjiggy said in Pi marquee 2 question:

if i use scraper will it automatically update the png files for other systems im using?

For games yes, you can use the scraper - but you'll need to use and external scraper like Skyscraper to get marquees, the built in EmulationStation doesn't support downloading marquees.

Marquees for systems are not so common, but you can look for logos on the scraping sites. For instance, ScreenScraper.fr has a page for each system, with a Media section where various artwork for the system exists.

Or should i create my own png for systems like megadrive,nes etc

That's always an option.
