Linking physical GBA to Dolphin 4.0

[jAquaD]

I have this Mayflash GC to PC adapter which works perfectly fine with Dolphin for both GC controllers; both inputs work for both of my controllers. I have a GBA-GC link cable, but it doesn't seem to be recognized by Dolphin. I tried going in to config, changing socket 2 to GBA, nothing. Has anyone had any success using the GBA-GC link cable on Dolphin? Main reason is to connect my physical sapphire cart to Colosseum iso.

Physical GBA-GCN links won't work. Dolphin only connects to GBA emulators that emulate the GBA's Joybus connectivity properly. The two emulators work together over a network (usually local). You can connect a GCN controller via Mayflash to your computer because Mayflash translates the GCN input into data over USB that your computer can see as buttons. In all likelihood, it doesn't translate any input data the GBA sends over serial output, especially since it's a bit outside of the Mayflash's scope (only advertises GCN controller input as far as I know, not the GBA-GCN connection).

The GBA is more complex than a simple joystick (has its own interrupts, memory map, CPU/LCD/APU to handle), so it's no wonder that Mayflash avoided implementing it.

It is not possible to link a real GBA console to Dolphin at this point in time (Dolphin 4.0).
