in the jp version we don't get to see jonouchi's internal "good guy" voice arguing with marik. it's basically him being totally silent as marik orders him, and he suddenly takes a different card and reasons it as "i dont need monsters to kill you..."
amusingly, a big deal is made out of the fact that Joey's deck is specifically changed to a Burn deck in JP. This is actually against Battle City Rules and pisses Kaiba off more than it being a battle to the death
the 4kids version continues to kind of ham up and make things a lot more repetitive as they talk, so there's some information we miss out on in the eng version... marik seems certain rishido (odion) won't betray him for some reason
in eng this card comes from an anonymous individual much later, and he takes it to heart as a sign his dad's still out there. in jp though... he gets this card years later...
so you may recall, the 4kids version changed it so kajiki/mako believes his dad survived somewhereand has been looking for him all his life, but in jp he knows he's dead
