Individuals have created small versions of Linux for compact ARM boards. These are tiny but not suitable for gaming, as 64Mb is insufficient for most applications. Running DOS on ARM would require an emulator and would demand more than 64Mb just to function. Even with a working Linux installation, you'd still need drivers for video and sound, which would consume all available RAM and CPU resources—making it unlikely to run complex games like Snake.
There are no speakers included in this watch, which is why the cost is 0.50 cents—what you should expect. Regarding the drivers, you can find them where you need them. For flashing instructions, there’s a USB port that allows connection to both your PC and Android device, but only via an OTG cable for Android.
There are multiple challenges to tackle before we even consider installing an operating system on the device:
What microcontroller is it based on?
Which I/O pins are available on the PCB?
How is the I/O setup on the microcontroller? (this might not be a critical question)
Even if you could determine all these details, you would still need to create a tailored Linux build for this particular hardware. Standard versions are too broad for such a specific setup.
It's likely that for a smart watch, it uses an ARM Cortex-M0 or similar processor, which isn't very powerful. Definitely insufficient for the 3D complexity of Doom 64. And even if you manage to get an OS running, simply installing any application won’t work. Most specialized embedded Linux distributions don’t include a package manager comparable to Debian’s apt.
To be honest, from what you’ve shared, the task you’re aiming for is well beyond your current abilities. If you struggle with addressing these issues, it’s best to wait until you develop more expertise in embedded systems.
