This is probably a very stupid question.
Would it be possible to create a C2 game for Dreamcast?
Short answer: no.
Even if you would port NW.js or Electron to Dreamcast, the processing power is too low for HTML5 games.
You could take the case of a Dreamcast and put a Raspberry Pi inside to run C2/C3 games.
I would love to use it for Mega Drive games instead, what a pity...

Thank you all for the replies, I will think about the Rasperry option
