Bubble Bobble has been extensively hacked.
There are a few Bubble Bobble editing utilities. Of the three, Bubble Bobble Level Editor is the least advanced. The other two edit the same data mostly.

Bubble Bobble was also released as an MS-DOS PC game for IBM and compatible (some high-end Tandy computers from the late 1980s could run this program as well, but not compatible for Amiga, Apple, or Commodore 64.)
