unfortunately its not gonna be easy lol, basically in SN you’d select a region and name it something like Dio_walk_1

Select all the next ones, name them Dio_walk_2, 3, 4, 5, etc then import – the underscore+number will turn them into a single SpriteGroup object where you can change the number in the sidebar for what “frame” is displayed

and then do that for every other walk, jump, etc sprites

it’s a lot of slow tedious aligning of the sprite box and selecting new regions
