COSOM GAME PRESERVATION

DEVELOPMENT UPDATE · NOVEMBER 2, 2026

Lagoon returns to the browser.

The supplied US cartridge provides an original English edition, so no translation patch is needed. This release adds the local SNES player, independent health and magic assists, controller and touch controls, snapshots with exported backups, and an ordered manual checklist through the ending.

Finished tasks move into Completed and the remaining list closes up. Checks persist in this browser; undo, uncheck and checklist file backups keep progress editable. The guide is included in Lagoon snapshots so it can travel with a saved game.

The original archive, cartridge, X68000 disks and personal saves remain unchanged. The browser runs the original game through EmulatorJS / Snes9x; this is not a native reconstruction or X68000 translation.

Verification covers actual English startup and opening dialogue, runtime cheat writes and removal, guide persistence/undo/import, and snapshot save/restore. The full campaign has not been replayed, and physical controller behavior has not been independently verified.
