a lot of the jumpiness in the sprites for the Apple II version is because in "hi-res" mode each 2 bytes gets you 7 pixels, so it's a lot easier to do sprites that are 7 pixels wide. Every other system tends to have 8-pixel wide sprites. So it makes it hard to convert graphics (you could make arbitrary-sized sprites but it's a lot slower and often involves large complex look-up tables) back in the day the reverse caused problems too, you can look up the grumbling of people porting Prince of Persia to non-Apple II systems and having to convert all the multiple-of-7 graphics to systems expecting things to be multiples of 8
