Kaboom! was pretty much an Activision rip on the original Atari Avalanche arcade game. As indicated, the originals in both cases used a potentiometer based control, with a hard end stop. Avalanche works fine, and reverses as soon as turned in the other direction, but obviously stops once the edge of the screen is encountered. It's not too hard to adjust your play to account for this (I have, and it's easily one of my favorite games).
Kaboom!, on the other hand, is hampered by the paddle control emulation. There's a long post
here (some language NSFW) which lays out the issues. It seems like fixing the basic "buffering" issue wouldn't be too difficult, but I don't think it has been done yet.
Regardless, these types of games absolutely require a high resolution spinner. A potentiometer is an analog, and in this case 8-bit control. This means that for whatever portion of a revolution the control allowed, it was capable of about 256 positions. A low resolution spinner can still provide that number of positions, but may take more than a complete revolution to provide it. The other alternative is to move more than one position at a time, making the control less precise. Neither are a very good alternative for these types of games.
