128x72 on Genesis - 112x64 on SNES
Counting how many frames are repeated in one second, you can see that the SNES version runs at 30 fps and the Genesis version at 20 fps.
That's kind of a huge difference, they could used the same rendering size and level layout on SNES at 20 fps too. I don't know why they changed... maybe they disliked the framerate on Genesis.
The level still good tho, it just have some colision problems (Woody feels kinda fat).
Both versions also has a neat trick in one level, a background CPU rendered to look like 3 layers in one.
