I'm doing this Commodore-64 Compatible & Gameboy-compatible retro computer for retro gaming that is extremely affordable ($25, 50% off for early customers)
You can find details and how to pre order on the website:

One thing I discovered with the C64 Maxi was how more important is the physical factor then the perfect emulation. The fact the thing has a C64 keyboard maintains the illusion it’s an authentic device.
