Happy 30th Anniversary, Princess Daisy!
Super Mario Land gets a full colorization hack by toruzz called Super Mario Land DX which changes the original Super Mario Land into a Game Boy Color game. Celebrating Daisy’s 30th Anniversary of her gaming career on Easter Sunday in 2019, a colorized remake of Super Mario Land was made to celebrate the occasion.
The full colorization of this game remakes the 8-bit original with updated graphics for enemies and characters to resemble the modern Mario games.
