GBA and Wii GCN Adapter

[charlie22911]

Hello all,

I have a couple of GBAs and GCN > GBA cables here along with the Wii GCN adapter. Attempted to give Zelda 4 Swords adventure a whirl but it seems this has not been implemented yet.

I'm not anything close to a coder but if anyone wants a beta tester to try some things I'd be more than happy to give some test builds a whirl and report back!

So let me get this correct. You bought the Official GCN Adapter or some kind of third-party device with the same purpose? Then you used the GBA <-> GCN cables too?

Well, bad news, but this isn't going to work. It's just technically infeasible at this time. The GBA sends data via serial input/output, but the GCN Adapters don't give us a way to look at the raw data being sent into the device. All it does is act as sort of interface that translates input from GCN controllers into something that looks like it came from a regular HID controller over USB.

Is it possible that we'll find someway to take a peek at the serial input going into these adapters? Maybe, but keep in mind that the GBA <-> GCN connection had very, very tight timing requirements, so even if we did get that far, the latency involved for Dolphin might still be an issue.

Thanks for the reply,

Yes I have the official Wii>GCN adapter and official GCN>GBA cables.
I did purchase the Wii adapter explicitly to use dolphin with my GCN controllers, I've had the rest for quite some time though; everything is official Nintendo gear.

I hadn't considered the HID limitation, though I was aware of the serial nature of the GBA link port and timing constraints.
