Bomberman - odd cheat?

[Quto]

I don't really know if this would be fascinating or not, but hear me out for a second.

Between the two games, Bomberman GB and Bomberman Pocket, they both share a common yet odd relationship.

Bomberman GB is the basic bomberman where you plant bombs, break blocks and get power-ups. Though with the defeat of each stage boss, you get a special upgrade; While Pocket Bomberman is nothing more but a platformer with the same principle as bomberman GB.
Both games include a password feature to allow you to jump to certain levels since the GameBoy cartridges never saved your progress, however there is a cheat code that gives you all the upgrades between both of these games.

Between both games, this is the big cheat code between the two to gain all power ups and upgrades without trying. I've tried my hand at a little research to try and find the programmers who had a hand in programming both games and see if its a repeating pattern...

While I don't really have any proof as too why, I think its an interesting thought to pt into consideration.
