We've seen some extraordinary portable N64 case mods in the past, but none functionally as well thought out and designed as this. It's a portable N64 mod known as the D64 and it'll play multi-player games. The funny thing is that the D64 uses the five-inch LCD from the old Sony PS One, how about that? Each charge can generate up to three hours of play time.

Here are the D64's official specs, according to its creator…

• Official Sony PSone 5? LCD screen
• 4 amps of battery power yielding a little under 3 hours play time between recharging
• SuperPad 64 Plus controller
• Nintendo 64 console motherboard
• Combined memory pack and rumble pack
• Expansion pack
• Built in speakers
• Weighs just under 1kg, is easy and comfortable to use, all controls in the right place!
