It always seemed like there must be a soda machine lurking somewhere in the Double Dragon series, and I finally found these in Double Dragon II for the Game Boy!
Of course, it’s worth noting that the Game Boy release of Double Dragon II was actually a re-skin (soda machines and all) of Nekketsu Kōha Kunio-kun: Bangai Rantōhen, an entry in the Kunio/Nekketsu High series.
Yet again, soda machines provide a unique window into video game history.
