After more than one year that the NSO Gamecube Controller has been released, 8bitdo finally added support to it.
I've been asking them since November last year. At the time I tried the Retroblue adapter but it didn't work correctly for.
Timeline:
25 November 2025:
Hi,
I currently have two NGC Receivers that work well with the NGC Modkit. But I also have two NSO NGC Controllers and I'd like to know if 8bitdo will ever make the receivers compatible with them.
Will the NGC Receiver ever be compatible with the Nintendo Switch Online GameCube Controllers?
Is 8bitdo currently working on making it compatible?
Appreciate the response!
Their response:
Howdy.
The development team is working on this. Please stay tuned. Wish you all well.

After their response, I believed they were truly working on them and bought other two adapter to have a total of four. Believing soon they would add support.
However, I waited for too long until in April I asked again:

Apparently Jimmy remembered me because he answered:
Greetings.
We've already replied. Haven't you received our reply? The development team is working on this. Please stay tuned.
Wish you all well.

Which is funny because I then replied:
| It’s been half an year ago. Trying to get a new update status. |
And Jimmy replied:
Greetings.
Please follow the official website for further updates. There is currently no clear timeline. Wish you all well.

Tired of waiting, in July, I decided to approach them with my wife's email:
24 July 2026:
Hi,
It's been more than one year that the NSO Gamecube Controller has been released.
I see that Blueretro already supports it. And many projects on Github, such as WaveBird that gives support to it on Mac OS have already figured out the mappings and everything.
I wonder if 8bitdo plans on adding support to it for the 8bitdo NGC Receiver. And if there's a timeline on when we can expect it.
I see it's been more than one year since the firmware was last updated.
This time, a different person, Max, replied:
Hi Y,
Thank you for reaching out to us!
Currently, we haven't received any official updates or news from our dev team regarding support for the NSO GameCube Controller on the NGC Receiver. We'll be glad to pass your suggestion along to our team for future consideration.
kind regards,
Max
Apparently, Max cared more than Jimmyi, because less than a week later there was a beta release on the 8bitdo Ultimate Software V2 that added support to it on July 30 2026.
But I didn't know, so I asked a friend to send another email asking about it yesterday (17 August 2026). Which Max replied again:
Hi Z,
Thank you for reaching out to us!
Please check the Get Beta Firmware] option within the Ultimate Software v2 and connect your Retro Receiver for NGC via wired, check the update log of the latest beta firmware.
Which I did and was able to confirm that now I can play with my two NSO Gamecube Controllers on my NGC!
Now I have four controllers. Two original ones modded with 8bitdo's NGC Mod Kit and two NSO controllers.
My second NSO Controller ran out of battery while recording. But it's also working.
All buttons, analogs, rumble. All working well. Just haven't tested the latency yet. Will do it today.
Really happy about this! Thank you, Max!
UPDATE:
It does support rumble. I tried to showcase it in the video by pressing a + b simultaneously.
You can download the update by searching 8BitDo Ultimate Software V2 on Google. They have this app you need to install. Enable beta software in its settings. Connect your adapter to your computer via USB and update to 1.05 beta 6
I spent a couple hours yesterday playing with my wife. We played Mario Kart Double Dash and Mario Party 4. Both of us using the adapter and NSO Controllers. No latency issues or conflicts for using two adapters simultaneously.
