This is the arcade version. I drew a box around Hawk and Ken.

This is CCC2. I copied the exact same boxes from above and pasted them onto this screen shot. You can see that CCC2 is squished horizontally and vertically, so the character heights and widths appear smaller.

For reference, here are the other console versions compared to the arcade:
PS1
Dreamcast
AE
