missing Namco/Bug-byte´s

Namco games which Bug-Byte published as TAPE versions: -Dig Dug -King & Balloon -Warp & Warp -Rally X -Tank Battalion I am not sure if GALAGA is also published as Bug-Byte´s TAPE. Thought I cannot think any reason why it is not published, as "every other namco game" is. Does anybody know this? Do you know if Bosconian and Tower of druaga are also published by bug-byte? other namco/bug-byte games seem to be in database, if I am not wrong.
