Lost NES prototype Xcavator resurrected as a playable VGHF fundraiser
iam8bit and the Video Game History Foundation have partnered to release a lost 1991 NES prototype, with all profits supporting game preservation.
Boutique publisher iam8bit has partnered with the Video Game History Foundation to release Xcavator 2025, a fully functional NES cartridge based on a previously lost 1991 prototype. According to the official announcement, 100 percent of the profits from this physical release will fund the foundation's ongoing preservation efforts.
The game originates from the archives of the late Chris Oberth, a programmer at Incredible Technologies known for coin-op staples like Golden Tee Golf. Oberth originally developed the title in 1991 and shopped it around to various publishers. The industry apparently shrugged at the time, resulting in the code sitting in an archive for over three decades until Oberth's family donated his materials to the VGHF.

Excavating the Code
This isn't a modern homebrew game wearing a retro costume. The VGHF rebuilt the title directly from Oberth's original source code. To bridge the gap between a 1991 prototype and a shipping product, the foundation collaborated with Mega Cat Studios to complete the game. The team specifically used tools and development environments consistent with what Oberth would have utilized during the original production window.
The result is a puzzle-platformer that feels authentically of its era, mostly because it actually is. It captures that specific early-90s energy where developers were still figuring out exactly how much abuse a player would tolerate before throwing a controller.
A Physical Artifact
The physical release follows iam8bit's standard premium packaging model. It includes a 14-page manual featuring historical context and information about Oberth written by VGHF staff.
"100% of the profits from the Xcavator 2025 NES Cartridge will go to fund the Video Game History Foundation," iam8bit stated. "[It is] a 501(c)3 non-profit organization dedicated to preserving, celebrating, and teaching the history of video games."
For collectors, this offers a rare opportunity to acquire a "new" NES game with genuine historical provenance rather than just another shelf-filler. It also serves as a reminder that for every Super Mario Bros. 3, there are dozens of competent, interesting games that simply vanished into filing cabinets because a marketing manager in 1991 didn't see the vision.
