How do I make a console for flash games with Arduino?

Computers and cards are very expensive in the country where I live Even an old ThinkPad X61 sounds very expensive

Can you give me more low-budget card names or if there is a gerber file of a single-layer card that can do this project, can you throw it away, I can melt the card with acid myself and make it.

Everything in Turkey is so expensive that it is much cheaper to do.
