Summary
In the early 2000s, incomplete prototype versions of Donkey Kong and Donkey Kong Jr. for ColecoVision were discovered. Both cartridges actually postdated the ColecoVision releases and were seemingly ports of the versions from the Coleco Adam computer, which featured more levels and cutscenes. The games were re-compiled into hacked ROMs titled "Super DK!" and "Super DK Junior" respectively; the unaltered ROMs were never released.
