This Metroid themed DIY Arcade machine, typically referred to a MAME (Multiple Arcade Machine Emulator) is hooked up with 2 NES, 2 SNES and
2 N64 adapters (called adaptoids) built in for easy retro controller support. Also thrown
in is a glowing brain from the original Metroid. The build is well documented with plenty of photos to guide you through the arcade build process.
