Lego Batman, like all Lego games, is absolutely loaded with references and easter eggs. As well as recreating memorable scenes from the Dark Knight's storied history, it is packed with geeky, niche in-jokes. One such easter egg requires a Commodore 64 to actually make sense of.
As pointed out by Cabelsa over on TikTok, when Batman analyses something on his computer in-game, a short splash screen pops up to signify that the computer is booting up. Turns out that screen isn't just for show, as Cabelsa points out: "Did you see that? Did you catch that? Back up. That, my friends, looks like Commodore 64 BASIC."
