Found this odd.

I saw this video pop up in my YouTube feed and wondering if the creator actually spoke with Sanni or someone else? Seemed strange to me since he mentioned https://twitter.com/cartridgereader which is all in Japanese.

EDIT:

I just found that this has been addressed in the forum but for traffic coming from the video itself, a little reference point:

https://forum.arduino.cc/t/rom-reader-for-super-nintendo-super-famicom-game-cartridges/155260/1481

This is obviously our mistake.
No matter what we say, it will be an excuse.
I asked them to put a correction at the beginning of the sentence in the video description: Every Retro Game Collector Needs This! The All-In-One Device I've Been Waiting For! - YouTube
I will continue to give People the correct information too.

I had two requests for him to make the video.
"I have two requests about the video you are making.
Cartridge Reader is an open source project on Github 2.
2. cartridge reader design by sanni & great contributors"
That was conveyed incorrectly.

No matter what I say, it is an excuse.
I am so sorry.
I pledge to continue to pass on the correct information.
