DraStic

There is no projects for the future to add multiplayer support on Drastic. There are many reasons for this.

How the Nintendo DS connects to other consoles or on the internet is very poorly documented, so its really hard to program multiplayer support from scratch.

There are some open-source DS ...

I think it would be possible thanks to the project https://wii.guide/wiimmfi.html
https://wiimmfi.de/
It allows plays old wifi games in Ds consoles and wii. I would try on DraStic
