Linking GBA to GC issues

[chaocaster_]

So I want to play Sonic Adventure 2 Battle for GameCube so I did, but now I want to get gold chao for some shiny chao (the sparkly/glistening ones) so I downloaded VisualBoyAdvanced-M and tried to link it and, it didnt work.

In controllers I have port 1 - standard controller | port 2 - GBA | (all other ports empty)
In VisualBoyAdvanced-M I used the Link option but it didnt work and I set the VisualBoy to GameBoy and it still wont recognize it.

Help me out please...
