Odyssey Local Co-op v0.1.0-alpha.1

v0.1.0-alpha.1 release notes

Odyssey Local Co-op's first public alpha adds a second full player actor to Super Mario Odyssey 1.0.0 for local same-screen play on Ryujinx.

Highlights

• Separate P1 and P2 controller routing with a distinct green P2 costume.
• Shared co-op camera with midpoint framing, adaptive zoom, and right-stick input from either player.
• Recovery bubbles that return a separated or fallen player toward the partner.
• Tested support for regular stage transitions, selected 2D valves, captures, and cap ownership.
• Independent P2 health display.
• Reproducible pinned build, deterministic ZIP, SHA-256 checksums, and a Ryujinx-first installer.

Important alpha limitations

• Requires Super Mario Odyssey 1.0.0 and normal in-game 1P mode.
• Ryujinx is the primary packaged target. Actual-Switch gameplay and Cascade-to-Sand travel are verified with the corrected Atmosphere payload; the public alpha ZIP does not yet automate installation of the generated main.npdm required by that hardware setup.
• The custom competition scoreboard is not distributed; competition settings remain disabled.
• Terminal-death recovery, some P2 health events, event-Moon scenes, and recovery placement still have known defects. Read KNOWN_ISSUES.md before playing.

Integrity

Use the .sha256 file published beside the release ZIP to verify the download before installation. The installer then checks each packaged file again before copying it.

This release contains no game executable, keys, firmware, save data, or stock Nintendo archive.
