How to make Nintendo's [Game & Watch] games?

So like this video,

How to program above game? What language or tool or editor it used?

How to make like that game?

That usually depended what display and other set of hardware you have and then you made and customized tools for that set (lcd sprite editor, etc.), it was mostly C/++, ASM, etc.

If you want a hobby project it’s things like raspberry, spark core, arduino with some led/lcd display and today there is wider range of languages to use like python or js based if you cant handle C++.

I want to make commercial product and I can handle only javascript and C#

I don’t think that is possible then. AFAIK most if not all of the cheapest, tiny and best performing components pretty much always require low level programming. If you want to use easier languages and tools your device will probably bulky and twice the size of a smart phone, have poor battery life and cost +$100 for the end user.

Hardware/electronics business is probably something you do not want to do commercially.

Then, I can learn C, so lets presume I know C, then what tool it would be using? If I write C code file via Visual Studio, then how can I input that to hardware?

You need to use the tools that work with the components that you decide to use, most likely something similar to gcc. You also have to choose all components that you will need in your product, make sure they work together and are safe. Then you look at the specs from each part vendor on how to control and use them via code and do prototype code.

Thx for reply. So what is ‘gcc’?

And so hardware needed, are there someone or company who can make that sort of mono chrome style screen handheld classic game console?

GCC = GNU compiler collection

I haven’t looked for but I don’t think any company makes ready game device templates like those old ones are because there is very limited target audience if they would be only programmers.

These games were just “hardwired”, so there is no code involved.

There are several circuit simulators if you want to try your luck:
