I downloaded the file, and the zip is empty. I've tried three different times and got the same thing. Help?

Which emulator are you using?

Depending on the emulator sometimes you have to use the inner zipped folder in its entirety (Deadeus folder) and some of them need the inner GB file to work. for emulators I would recommend either BGB on PC or MyOldBoy on mobile. Hope this helps!

I figured out the issue. I was trying to DL from itch.io's mobile site. It works now.
