Thanks to Delta, a popular iPhone emulator, Nintendo DS fans can soon enjoy online multiplayer support for their favorite retro titles.

On The Verge, Riley Testut revealed the multiplayer functionality leverages melonDS’s online multiplayer code and connects through 3rd-party servers, allowing any Delta user around the world to compete in games like Mario Kart DS as they did back when Nintendo servers were still operational. No official release date has been set yet, but Patreon subscribers will have access to a beta version before it goes public. The service is set for free once available, just like the rest of Delta.

What are your favorite retro DS multiplayer games you’d like to relive using Delta’s online functionality?
