🔗 GamerCard is an ultra-thin emulation handheld
Created by Grant Sinclair, the nephew of the inventor the ZX Spectrum 8-bit home computer.
I don't know how I haven't heard of this before, but GamerCard is a Raspberry Pi based handheld in a very thin package. It's just 6.5 millimeters thick (thin?), powered by a Raspberry Pi Zero 2W, and features a 4-inch 60 FPS 1:1 screen.
At £125 (around $170), it ain't cheap, but it should handle systems like NES, SNES, Sega Genesis, Game Boy Advance, and maybe some PlayStation 1 titles.
