Undertale fans have partially ported the 2015 indie icon to its natural home, 1998's Game Boy Color.
Undertale has a ton of classic Nintendo in its DNA, the game is clearly inspired by the likes of Earthbound (and to a lesser extent Mario & Luigi, I'd say) and some of developer Toby Fox's earliest works are romhacks for Earthbound (the first version of the iconic boss fight theme Megalovania appeared in one). And while it's perhaps a bit too elaborate to have existed on the SNES or any other classic Nintendo console, that hasn't stopped fans from trying.
