This game has hidden developer credits.
The popular multiplayer mode makes it to the NES. And the people rejoiced.
This enemy is named Kondoria and it's seen in the TurboGrafx-16 Bomberman game as a battle mode obstacle, but it's not seen in this game.
To check whether the game was hard or soft reset, the game uses the string
A string with the game's name appears at the end of each version's ROM. The North American and European versions also have build dates.
BOMBER MAN 2
These passwords toggle various features in the game.
Entering this password leads to the first area's bonus stage. After that, the player is thrown back to the title screen.
|PBOMBACE||K2JG2135||Shorter Bomb Timer|
Bombs sit shorter before detonating (1 second).
|PBOMBOLD||K2JG2JF4||Longer Bomb Timer|
Bombs sit longer before detonating (3 second).
|PBOMBMAN||K2JG2G1H||Reset Bomb Timer|
Resets the bomb timer to its default 2 second delay.
Remote bombs are always enabled in 1P mode.
Enabled remote bombs, but bombs will detonate by themselves if left around for too long.
It's a sound test. Duh.
The trademark info was updated in the North American game, and a trademark symbol was added. The European version changes the title entirely, not only because the first NES Bomberman never came out in Europe at the time, but also because the original title was associated with terrorist bombings (at the time).
The cross on the church was removed.
As evidenced above, the password format is different between the Japanese and International revisions. The international release omits all vowels, an odd bit of censorship(?) that can be seen in other games. Though the symbols changed, the actual password values are identical. A=1, H=8, I=B, etc.
Spaces were removed between Bomber and Man, and Man and 2. The European game remembers to update the game title.
