Eyepatch Updates Playable Super Mario 64 3DO Conversion

Eyepatch Entertainment has released a new update for its Super Mario 64 conversion targeting the 3DO, bringing the project noticeably closer to something that can be played on real retro hardware. The latest video highlights improved performance alongside ongoing rendering trade-offs—and it also confirms a Sega Saturn version is planned, though it’s not ready to show yet.

Update improves visuals, but performance still isn’t locked

After unveiling an early 3DO build last week that already showed recognizable elements like Peach’s Castle and Bob-omb Battlefield, the developer has now shared a fresh update demonstrating further progress. Eyepatch Entertainment says the frame rate is “better and worse” than the previous showcase, explaining that enhancing the renderer’s look takes time—creating a balancing act between performance and visual fidelity.

In the new demonstration, the project still shows jitter, and the team is continuing to refine how 3D assets are drawn and adjusted based on proximity. Even so, the developer frames the current state as getting close to a playable conversion on the actual console, with classic gameplay moments included—such as penguin rescue segments—while avoiding the joke “baby yeeting” scenario shown in other contexts.

What changed

New 3DO video update for the Super Mario 64 conversion
Frame rate behavior adjusted—described as improved in some areas but worse in others
Rendering improvements underway, with the team explicitly trading off fidelity versus performance time
Ongoing work on 3D asset rendering and proximity-based behavior
Demonstration includes penguin rescue gameplay segments

Platform scope: 3DO now, Sega Saturn later

The project is centered on bringing Super Mario 64 to the 3DO, and the new update is specifically tied to that hardware. Separately, Eyepatch Entertainment also indicated a Sega Saturn version is being worked on and is intended to run at 60 frames per second, but it isn’t ready for a further reveal yet.

While some players have asked for an ISO for use in emulators or on actual 3DO hardware, the developer says they’re not planning to distribute it, citing concerns about Nintendo’s potential reaction to distributing the project.

What comes next

Eyepatch Entertainment’s own framing suggests the immediate challenge is refining the renderer without sacrificing stability—especially as the conversion continues to address jitter and proximity-based 3D behavior. In the meantime, the Saturn build remains a future goal, with the developer signaling that a 60fps version is possible but still not at a stage where they want to show it publicly.

The developer also left a blunt note about the distribution question: if it were feasible to share it safely, they would, but until then they characterize the current state as essentially a personal achievement on 3DO hardware—while acknowledging how risky it could be from a rights perspective.
