I know EBS exists (and EBSDX is on the way soon), but let's just say you don't want your project to include it, and the only thing you really want from it are the animated trainers feature (for special trainers like rivals and gym leaders etc.), or just little Pokémon entrance animations from pre-gen 5 (so not fully animated throughout the battle). How possible would it be to include trainers or Pokémon being animated once through a spritesheet, and where exactly would I start with adding something like that?
