Bubble Bobble Part 2 (NES)

Bubble Bobble Part 2 is, obviously, a sequel to Bubble Bobble without a co-op mode, though its "Part 2" status is debatable, with the simple "2" for the Japanese release being more debatable.

Unused Title Screen#

Ending scene palette	Unused palette

Graphics and 16x16 metatiles for an alternate title screen can be found in both the Japanese and US ROMs. Though the actual screen layout no longer exists, the ending scene (which was based on the old title screen) can be easily modified to show what it probably looked like. It's worth noting that the logo fits perfectly inside the existing cloud arrangement.

The image on the left shows the palette used in the ending scene, while the one on the right shows an unused palette, which is identical aside from the purple color seen in the logo.

Early Graphics#

Older versions of some existing graphics can be found in unused areas of the Japanese PRG ROM.

To do: Assemble the sprites as they would be seen in-game.

HURRY UP!#

Early	Final

Ditched in favor of a complete character set. The lower half of the 8 and the 9 are much blockier than the final versions.

Skel-Monsta#

Early	Final

Judging from this lone tile, it appears that Skel-Monstas used to be much more evil-looking.

Bubble#

Early	Final

Bubbles used to be solid, similar to their arcade counterparts. The solidity might have made sprite flickering more apparent.

Corn Dog#

Early	Final

Two colors were swapped on this cholesterol-laden treat.

Rounder#

Early	Final

Another sprite that had its colors swapped.

Roc#

Early	Final

Roc got a glossy coat of paint and bigger shoes for his official debut.

Super Drunk#

Early	Final

Nothing but a palette swap for this pushover of a boss.

Round Differences#

To do: Check the remaining rounds for differences; If this section gets too big, make a subpage.

The North America version has fewer enemies overall. This does make a sub effect however, that some hidden items are harder to discover as their counters are tied to enemies and their drops.
