The individual PNGs are mixed together correctly, though. Therefore, there are strips labeled 'Extra' in the corresponding folders that contain the correct new sprites in the positions (I didn't feel like opening the images and stitching them together into one strip). Sonic and Tails in S&K have extra frames from S&K that aren't in S3.Each MMD uses a certain set - even though there're 70 level MMDs, there are only 4 different versions of Sonic's data. Tails' tails are separate images for obvious reasons.(Mind, though, some origins will not be correct: for instance, Sonic's spinning sprite needs to be moved 5 pixels down because this offset is added to object's position in the real engine before displaying the sprite.Each frame is rendered centred on a 64圆4 canvas.I've ripped them both as separate PNGs and as horizontal strips.It doesn't really matter - you probably won't want to load the blank ones anyway, they're just there to space it out so that the frame ids match. Entirely blank frames come out black instead of transparent this is a quirk of GM that I haven't licked yet.
