Just for curiosity, how does the old Game&Watch games work? Can they be emulated? Do they contain some kind of ROM that can be dumped, or is they made of some simpler logic?
Google didn't tell me much...

Looks like emulators come with game.
Also,look here:

There's more of them.
But i don't really know if they really a emulators,looks more like remade games for PC.
But it's still fine,isn't it?
Indeed, they're not emulators, just remakes.
Too bad for my hopes of a
PCPStation emulator that can run Chanticleer Hegemony. (POPStation is a line of Chinese Game & Watch-style games with interchangeable display cartridges, similar in concept to MB's
Microvision and Tiger's
R-Zone.)
think i heard someone saying they use some kind of custom(?) 4bit microcontroller with on-die rom. only a decap will let us know.. but is it worth it?
all systems that can be made can also be emulated, it's just a matter of time to RE it and fps in the emulation
The LCD screens are like a calculators sept it had the games graphics built into them rather than just straight lines and the rest of the graphics was stored on a peace of cardboard, how would someone go about emulating that?
So we have up to a 250-segment liquid crystal display. Make an indexed-color image the size of the display, and have the value of each pixel represent which segment it belongs to. Then use palette animation to turn each segment on or off.
yeah but you would still have to recreate the graphics so idk if you would call it true emulation
peppers: do you also mean that it's not possible to emulate a vectrex due to it's impossible to draw vector art on a raster display?
...sure you have to simulate the display but you could still emulate the game logic

A lot of these LCD games turn on all segments briefly during power-on self-test. Dump this image with a camera.
or you could disassemble it and power the entire screen and place it in a scanner and scan graphical paper backer as well. I guess it is kinda possible. although it might be better if you could turn on one segment at a time.
I think those simulators already got the LCD layouts in with similar methods (that's what I remember from checking them years ago, but it was a long time)? Or, did they just painted them to recreate the images from a reference photo?
You can also try to look how the russian Game and Watch reverse engineered games looked like here in europe, and don't forget to check the download section and the About Site- there's the main microprocessor mentioned - КБ1013ВКxxx:
