I've had this idea floating in my head where someone could use a modified version of Nintendont on a Wii/Wii U to play GC/GBA link cable games (such as four swords adventures) with a DS or a 3DS. The basic gist of it would be to use wii-ds-rom-sender to send a ROM of GBARunner2 patched with the GBA BIOS ROM to a DS' downloadplay (similar to how wii-ds-rom-sender can already send patched versions of GameYob and nesDS with GBC and NES ROMS injected into them), then Nintendont connects to GBARunner2 wirelessly to begin the GC/GBA link cable process.
I haven't seen any ideas like this elsewhere and I don't think it's completely unfeasible; here is a POC of GBARunner2 playing a GBA game multiplayer with the DS' wireless networking (and is available to try here) and the GBARunner2 + GBA BIOS Rom would be under the DS' 2MB of ram so I don't think there would be any issues loading it onto a DS. Nintendont and wii-ds-rom-sender are both developed by @FIX94 so perhaps they could be merged into a custom Nintendont release that allows ds-download-play functionality to start as soon as the GameCube game boots.
I think the biggest issue I see is getting Nintendont and GBARunner2 to communicate wirelessly, as GBARunner2 has made no development on this type of connectivity at the moment. So I guess this post is more of a "can this sort of thing be done" since I'm sure I don't understand all of these systems completely, and maybe the environments in which these systems work in are more sandboxed than I realize and so they just can't communicate between each other fundamentally.
Either way, I think that this concept by itself is really cool and if works out, it would make the games that use this kind of feature so much more accessible when utilizing wireless ds connectivity alongside a wii and I think so many people would be able to experience games like four swords adventures and crystal chronicles for the first time.
