Download Index failed for Game & Watch

And this gives a 404 http://bot.libretro.com/assets/cores/gw/

Anyone know how I get all of the games and overlays?

The URL changed. It’s this now: http://bot.libretro.com/assets/cores/Game%20and%20Watch/ You should be able to download everything through the ‘add content’ menu.

That’s where I was doing it but it says failed. What should I do?

Doesn’t matter, just downloaded them manually.
