In 2015, the author of this document asked on the public forums how to insert Drunks in Karl Stenerud’s Patch-A-Bobble, an editor for Bubble Bobble on the Arcade. The answer is, you can’t, but you can with a hex editor, and through comparing files to each other, QuietWhisper figured out how.

This guide will teach you how to insert Drunks in Bubble Bobble while hacking, and will provide a table of the hexadecimal offsets for each level up to Level 99.
