X-Men is one of the few video games in history which requires the use of the Mega Drive's reset button in order to progress through a certain point in the game. This means the game is impossible to beat when played on systems (or emulators) which lack a soft reset feature of some description.
This game became infamous for it's high difficulty level, which stems from the game's awkward hit detection, lack of continues and difficult to grasp boss battles and stage layouts. While plenty of shortcuts (mainly through Nightcralwer) and failsafe boss strategies (e.g. a full health Wolverine can take every hit from the lighthouse boss and still win) exist, these were made difficult to explore by the way the game was designed.
