The National Videogame Museum in Frisco, Texas has just acquired the Holy Grail for collectors: the Sony MSF-1, the very first development prototype of the Nintendo PlayStation. This one-of-a-kind unit, even predating the known commercial prototypes, bears witness to a time when Nintendo and Sony were allies before their legendary split that ultimately gave birth to the modern PlayStation.
The MSF-1 is not just another prototype. It is the original development system for the CD add-on Sony was designing for the Super Nintendo in the early 1990s. Unlike the more advanced prototypes seen in recent years (including one that sold for $300,000 at auction in 2020), the MSF-1 appears as a raw development unit that plugs directly into the SNES cartridge slot. Its utilitarian look contrasts with later versions, but its historical value is immeasurable.

This acquisition brings back one of the biggest “what if” stories in video game history. When Nintendo abruptly ended its partnership with Sony to team up with Philips instead, Sony was left with advanced CD technology and no partner. The result? The creation of the original PlayStation in 1994, which would go on to break Nintendo’s dominance and change the industry forever.
The National Videogame Museum states that this MSF-1 is “the only known surviving example.” Its preservation within a dedicated institution ensures that future generations will be able to witness this unique relic of a missed alliance that shaped the history of video games.
