1. N64Boy Advance

3. Portable NES Cartridge

File this under: custom portable gaming system and/or arcade machine. Instructables user “danny32412” was tired of the bulky NES system, so he used an old cartridge and a special miniature chip to create the ultimate custom console.

4. Atari 2600 Portable

Built by Ben Heck forum member “Mario”, this Atari 2600 portable features a 3.5-inch LCD, two Game Boy Advance SP batteries, and a functional cartridge slot. We’d go as far as saying that this custom game console should definitely be considered for worldwide release (limited edition).
