@John, getting DOSBox to work is fairly complicated if you don't know how ... Firstly, you can't just open the game file; you have to open DOSBox and then run the game from there. Secondly, you have to mount the drive first before you can access the game file. This requires a basic knowledge of DOS commands.
After installing DOSBox: In your Start menu, go to Programs > DOSBox > Configuration > Edit Configuration
At the very bottom of the Notepad file, in the [autoexec] section, paste the following two lines. This will make it so DOSBox starts out in the right folder:
mount C C:\Progra~1\Games
C:
Replace "C:\Progra~1\Games" with your own destination folder, wherever you installed Bubble Bobble. ~1 replaces the rest of the name for long folder names, because there is an 8-character limit in DOS. (Putting these lines under [autoexec] makes it so you don't have to type them every time you open DB.)
Then save and close Notepad.
When you open DOSBox, you may have to type something like "cd bubble~1" to
Change the
Directory to where Bubble Bobble is.
Then just type "install" to install, and "bubble" to play. Hopefully everything will work fine once you're in DB ... let me know if you encounter another problem.
