Just in case you or anyone reading this didn't know, there is a way to get EarthBound battle animations on your Android device today.

Edit: This app is no longer supported and fails to run.
I used to have this one which emulates the trippy backgrounds you had in battles in Earthbound.
If you have an Android phone, you can get this as a live wallpaper. I've used it. https://play.google.com/store/apps/details?id=com.miadzin.livewallpaper.earthbound
