If you say yes to this option, support will be included for the

USB Gecko adapter as an udbg console.
|

|
The USB Gecko is a EXI to USB Serial converter that can be plugged
|
||||||
|
into a memcard slot in the Nintendo GameCube/Wii.
|
||||||
|
|
||||||
|
This driver bypasses the EXI layer completely.
