Also pretty sure that if there isn't actually code heritage, the 7800 versions of those games were ported using the NES version as a reference. Is it possible Nintendo either programmed the 7800 version themselves, or actually provided the NES source code for Atari to modify for 7800 hardware? The similarities are too big to ignore (and too specific to the NES version versus the arcade version, which other computer and console ports tended to be more similar to).
