When the engine was reused for Gen 4 the implementation of 3D made the game run at 30fps as opposed to Gen 3's 60 which made the game feel slow as molasses and then Gen 5's engine had a similar issue except this time there was constant sprite stretching due to using really shitty filtering and no anti aliasing which led to interlacing on the older DS models too.
