The controls were flipped when the game was released outside of Japan. Instead of A jumping and B attacking, B jumps and A attacks in the US and European versions. This change extends to the cheat codes as well.
The title screen was completely redesigned for the English release, transitioning from the first screen to the second.
The European version omits the title logo completely (the CHR data is exactly the same as for the US version, but tilemaps for the title were wiped out), leaving it in basic text form on the earlier copyright screen. Two tall buildings were also added to the right side of the screen. A few tiles of the leftmost character's pants are miscolored in the first screen. Also, there are a couple of occasional pixels at the top of the rightmost building, but they aren't drawn there due to being a leftover "TM" sprite from the US title screen, missed while redesigning the European title screen. The tower and letters share the same palette, so some pixels of letters are invisible on the building, render this message unreadable and seems unnoticed.
Striker's portrait was recolored for the English release.
The Famicom version has stage intermissions that were removed in the English versions. Translations are provided alongside each image.
I will easily crush you. Let's see how quickly you get to me!
I... WILL... PULVERIZE YOU!!
I doubt that you can even navigate the cars to reach me.
So you've finally reached me. This'll be pretty fun.
This is the point of no return. Allow me to show you my vast power.
The ending in the English versions contain a staff roll that doesn't exist in the Japanese version.
