MiSTer is an open source project that recreates classic computers, video game consoles, and arcade machines using modern FPGA hardware. It can emulate arcade systems (Neo Geo, etc), home consoles (NES, Gameboy, Atari 26/52/7800, NeoGeo, SNES, Vectrex) and even home computers like the Apple II/Mac/IBM PC.

It will run you about $350-500 – or even more if you want add-ons. It also requires some complex setup; but it can generate some of the best emulation of retro gaming systems.
