A Lost Galaga Prototype for the NES Has Finally Resurfaced After 40 Years

There’s something fascinating about unreleased games from the early 1980s, especially when they involve companies that later became rivals. That’s exactly why this newly recovered prototype of Galaga for the Famicom, better known internationally as the NES, feels like such a big deal for gaming history fans. You can even download the prototype yourself here.

The prototype dates back to 1983 and comes from a little-known partnership between Atari and Nintendo. At the time, Atari planned to distribute Nintendo’s Famicom hardware outside Japan before the NES officially became what we know today. As part of that agreement, Atari secured rights to bring several arcade games to the console, including Galaga, Joust, Millipede, and Stargate.

Instead of developing those ports internally, Nintendo outsourced the work to HAL Laboratory, the studio that would later become famous for franchises like Kirby and Super Smash Bros. That alone makes this prototype feel like a bizarre crossover from an alternate gaming timeline.

What survived all these years wasn’t even a complete game. In August 2025, gaming preservationist Frank Cifaldi from the Video Game History Foundation managed to dump the prototype from a loose EPROM chip. The original program ROM still existed, but the graphics ROM had been lost somewhere over the decades. Because of that, enthusiasts had to reconstruct the visuals using arcade assets and elements from HAL’s other NES conversions to make the game fully playable again.

Even with the reconstruction work, the prototype still offers a surprisingly authentic look at what this version of Galaga could have been. And interestingly, it feels very different from Namco’s official Famicom release that arrived later in 1985. The shooting, enemy formations, and tractor beam mechanics are all recognizable, but the overall presentation has a rougher, more experimental style that fits early HAL projects from that era.

One of the coolest details is the Atari copyright notice sitting right there on the title screen. Seeing Atari, Nintendo, HAL Laboratory, and Namco connected through one unreleased project almost feels surreal today considering how differently gaming history eventually played out.

Of course, the collaboration never fully materialized. Atari’s financial struggles during the lead-up to the 1983 video game crash caused the partnership to collapse before these ports could officially launch under the Atari brand. HAL eventually released games like Joust and Millipede on the NES themselves, but this version of Galaga quietly disappeared because Namco already had its own stronger adaptation ready to go.
