Writing "Genesis" or "Mega Drive" instead of "GEN/MD" would run into trademark issues. While Sega takes a relatively benign attitude toward homebrew/indie games, IIRC they've asked that their trademarks not be used in that way, as it would give the impression that the release had their official blessing (or something along those lines).
