The Teenage Mutant Ninja Turtles: The Cowabunga Collection received its first patch, and it’s a hefty one. Headlining the release is online multiplayer support for Teenage Mutant Ninja Turtles IV: Turtles in Time and customizable button mapping.

For Game Boy games, dev Digital Eclipse also added more color filter options. Players can choose between black and white, Game Boy green, Game Boy pocket green, and Game Boy light blue.

And yes, the Switch edition’s Home menu icon has now finally been changed to the TMNT: The Cowabunga Collection’s box art–an inconsequential change in the grand scheme of things, but a welcome aesthetic tweak. The previous game icon included the four turtles without the game title, but that has now been changed to the cover art with the game title.

For more information, check out the full patch notes included below.

TMNT: The Cowabunga Collection released in August 2022 and bundles together 13 of the classic Teenage Mutant Ninja Turtle games. In future updates, Teenage Mutant Ninja Turtles III: The Manhattan Project (NES) will get online multiplayer support, too.
