Heavyweight Championship Boxing
|Heavyweight Championship Boxing|
This game has regional differences.
The Japanese version has a fuller menu, although, the only thing you can modify is the music. Maybe in 2-player mode it can be modified?
In the Japanese version, character names are parodies of real life or movie boxers. Such as "Mai Taison", "Aporo Food", and more.
The round girl looks like a Playboy bunny in the Japanese version. This was modified for the US release for obvious reasons.
Both versions display the round girl scrolled up by 1 pixel every round, so at the final 12th round we may see at least 12 more pixels of her lower body part. The Japanese version, additionally, has an Easter egg cheat: at the 12th round screen, hold Down, then quickly press A or B to scroll the girl's picture up to an additional 24 pixels, revealing a full picture. Although this Easter Egg is disabled in the US version, the girl's picture is also fully drawn, but can't be seen normally on the actual hardware during the game, rendering this portion of picture unused.
The Japanese version has the "ending" after beating the 5th opponent, but then you fight a 6th one, which nets you the credits. In the US version, beating the 6th opponent nets you both the ending and credits. The ending text are different between versions too.
Any mention or logo of the Japanese publisher (Tonkin House), was replaced with logos for the US publisher (Activision).
